We start by identifying the formula that links expected stock return, risk-free rate, market return, and beta. According to the CAPM (Capital Asset Pricing Model), E[R_i] = R_f + β_i × (E[R_m] − R_f).

Option-by-option analysis:

Option A: 1.38
- This value yields a close match to the given data. Compute beta: β = (E[R_i] − R_f) / (E[R_m] − R_f) = (0.133 − 0.013) / (0.10 − 0.013) = 0.120 / 0.087 ≈ 1.3793, which rounds to 1.38. Therefore this option is consistent with CAPM using the provided numbers.

Option B: 1.55
- If beta were 1.55, the expected return would be E[R_i] = R_f + β × (E[R_m] − R_f) = 0.013 + 1.55 × (0.10 − 0.013) = 0.013 + 1.55 × 0.087 ≈ 0.013 + 0.13485 ≈ 0.14785, or 14.785%. This is noticeably higher than the given 13.3%, so this beta overstates the stock’s sensitivity.

Option C: 1.33
- With β = 1.33, E[R_i] = 0.013 + 1.33 × 0.087 ≈ 0.013 + 0.11571 ≈ 0.12871, or 12.871%. This is lower than the provided 13.3%, so this beta underestimates the stock’s return relative to the CAPM expectation.

Option D: 1.41
- For β = 1.41, E[R_i] = 0.013 + 1.41 × 0.087 ≈ 0.013 + 0.12267 ≈ 0.13567, or 13.567%. This is higher than 13.3%, so it implies a larger beta than the correct value.

Option E: 1.23
- If β = 1.23, E[R_i] = 0.013 + 1.23 × 0.087 ≈ 0.013 + 0.107 (approximately) ≈ 0.12, or 12.0%. This is well below the given 13.3%, indicating a much weaker (smaller) beta than the actual.

Summary: Only option A yields a beta that aligns with the provided expected return using the CAPM relationship. The remaining options produce expected returns that are either too high or too low relative to 13.3% given the market and risk-free inputs.
