To approach this question, we first note the key signature shown: a minor key signature with two sharps, which corresponds to the key of B minor (relative minor of D major). In B minor, the scale degrees are: B (1st, tonic), C# (2nd, supertonic), D (3rd, mediant), E (4th, subdominant), F# (5th, dominant), G (6th, submediant), A (7th, subtonic in natural minor; leading-tone in harmonic minor when altered). Now examine the given note in the staff: with the two sharps in the key signature, the pitch shown aligns with C# when considering the scale of B minor.

Option-by-option analysis:
- tonic: The tonic in B minor is B. Since the note is C#, it does not function as the tonic. This choice misidentifies the scale degree.
- supertonic: This is the 2nd degree of the scale, which in B minor is C#. Because the note matches C# and occupies the second scale degree, this is the correct harmonic function.
- mediant: The mediant in B minor is D. The note C# does not correspond to D, so this is inaccurate.
- subdominant: The subdominant is E. The given note is not E, so this option is incorrect.
- dominant: The dominant is F#. Since the note is C#, not F#, this cannot be the dominant.
- submediant: The submediant is G. The note C# is not G, so this is not the correct function.
- subtonic: The subtonic in natural minor is A (a whole step below the tonic B). The note C# is not A, so this is not the subtonic.
- leading-tone: The leading-tone in harmonic minor would be A# (to lead to B), which is not C#. Therefore, this option is not applicable here.

Collectively, the only option that corresponds to the second degree of the B minor scale given the context is supertonic. The reasoning hinges on identifying the key signature as minor, locating the note as C#, and recognizing that C# functions as the supertonic in that key.
