We need to restate the problem and examine each answer option in light of CAPM.

Option 1: 1.33
This value would imply a beta slightly lower than the rounded result from CAPM. Using the standard formula E[R_i] = R_f + beta*(E[R_m] - R_f) with R_f = 1.3%, E[R_m] = 10%, and E[R_i] = 13.3%, we get beta = (13.3 - 1.3) / (10 - 1.3) = 12.0 / 8.7 ≈ 1.379. This is closer to 1.38 than to 1.33, so 1.33 underestimates beta and is not consistent with the data.

Option 2: 1.41
This value is very close to the computed beta of approximately 1.379, which rounds to 1.38. Some rounding conventions or data entry differences could yield a value near 1.41, but with the given numbers the CAPM calculation yields about 1.38. Therefore 1.41 is not the exact CAPM result for the provided inputs, though it is in the same vicinity due to rounding behavior.

Option 3: 1.55
A beta of 1.55 would imply a larger market risk premium relative to the stock than provided by the data. If beta were 1.55, the expected return would be R_f + 1.55*(E[R_m]-R_f) = 1.3% + 1.55*(8.7%) ≈ 1.3% + 13.485% ≈ 14.785%, which is far above the given 13.3%. This indicates inconsistency with the inputs, so 1.55 is incorrect.

Option 4: 1.23
A beta of 1.23 would imply a smaller required premium: 1.3% + 1.23*(8.7%) ≈ 1.3% + 10.701% ≈ 12.001%, which is lower than the given 13.3%. While closer than 1.55, it still does not match the provided expected return and, thus, is not the correct CAPM result for these numbers.

Option 5: 1.38
This option exactly matches the direct CAPM calculation using the provided inputs: beta = (13.3% - 1.3%) / (10% - 1.3%) = 12.0% / 8.7% ≈ 1.379. Rounding to two decimals yields 1.38. This aligns with the computed value from the formula and is the most consistent with the data, though note that the provided answer key lists 1.41, which could reflect a rounding convention or slight data variation. If you follow the standard calculation and two-decimal rounding, 1.38 is the precise result for these inputs.
