The prompt asks us to identify two muscles labeled A and B from a list of options. We will evaluate each label and compare it to the possibilities before concluding why the chosen options fit.

Option set for A includes: Gluteus Maximus, Gluteus Medius, Gluteus Minimus, Tensor Fascia Latae, Sartorius. 
- Gluteus Maximus is the large superficial buttock muscle primarily responsible for hip extension and external rotation; it is larger and more posterior than the structure typically labeled A in hip region figures, so it’s unlikely to be the correct match for A. 
- Gluteus Medius lies on the outer surface of the ilium and is crucial for abducting the thigh and stabilizing the pelvis during gait; this aligns with a lateral hip muscle recognizable in many diagrams as a distinct, upper-lateral muscle. 
- Gluteus Minimus sits deep to the gluteus medius, smaller in size, and also abducts the thigh; however, given typical labeling conventions, A is more plausibly the larger gluteus medius in many educational figures. 
- Tensor Fasciae Latae (TFL) is a small, lateral thigh/hip muscle that flexes and abducts the hip and tightens the iliotibial band; it is usually more anterior and superior to the gluteal muscles, making it a less likely fit for a label expecting a gluteal muscle.
- Sartorius runs obliquely across the thigh from ASIS to the medial tibia and is the longest muscle of the body; its movement is hip flexion, abduction, and external rotation, which is not the primary action you'd attribute to a gluteal label A in typical diagrams.

Evaluating these, Gluteus Medius is the most fitting match for A because of its classic lateral hip location and role in abduction and pelvic stabilization, which is a common target in basic anatomy labeling questions.

Option set for B includes: Tensor Fascia Latae, Sartorius, Gluteus Medius, Vastus Medialis. 
- Tensor Fasciae Latae (TFL) again stands out as the superior-lateral hip/thigh muscle that inserts into the iliotibial band and assists in hip abduction and flexion; given the question’s pairing with A as a gluteal muscle, B being TFL helps differentiate two distinct lateral thigh muscles.
- Sartorius is along the anterior thigh, crossing from hip to knee, involved in flexion, abduction, and external rotation; it is not a primary lateral hip abductor, so it’s a less likely B in a diagram focusing on hip/abductor musculature.
- Gluteus Medius, if chosen again as B, would create redundancy with A and is typically not paired in this manner in labeled diagrams where distinct muscle names are given for A and B.
- Vastus Medialis is one of the quadriceps on the anterior thigh and mainly knee extension; it has no primary role in the hip region labeling, so it wouldn’t be a correct fit for B in this context.

Thus, Tensor Fascia Latae is the best option for B because it is another prominent lateral hip muscle that complements the gluteus medius in many anatomical illustrations, and it differentiates from Sartorius and Vastus Medialis in function and anatomical location.

In summary, A = Gluteus Medius is chosen due to its lateral hip position and abduction/pelvic-stabilizing role, while B = Tensor Fascia Latae is selected to represent the adjacent lateral-hip muscle that integrates with the iliotibial band, distinct from Sartorius and Vastus Medialis.
