Betas measure an asset’s sensitivity (factor loading) to the specific systematic risk factors explicitly included in the pricing model.

1) Relevant knowledge points and concepts
- Systematic risk: risks that affect many assets (e.g., market, size, value) and cannot be diversified away.
- Idiosyncratic (firm-specific) risk: residual risk that can be diversified.
- In factor models (including CAPM or multi-factor models) an asset’s return is typically written as: return = alpha + Σ(beta_j * factor_j) + epsilon, where beta_j are the factor loadings, factor_j are systematic factor returns, alpha is abnormal return, and epsilon is idiosyncratic noise.

2) Complete reasoning process step by step
- Beta (or factor loading) multiplies a systematic factor’s return in the model equation, so it quantifies how much the asset’s return moves for a unit change in that factor.
- Because betas are tied to factors explicitly in the model, they describe exposure to those specified systematic risks.
- Betas do not capture residual idiosyncratic movement (epsilon) nor the alpha term (abnormal return). They also do not cover systematic risks that are not included among the model’s factors.

3) Calculations / intermediate steps
- No numeric calculation is required. The algebraic decomposition clarifies the role: return_i = alpha_i + beta_i * factor + epsilon_i (single-factor); beta_i is the coefficient on the factor term.

4) Why the correct answer is correct
- Option b states betas reflect “an asset’s exposure to the systematic risks explicitly considered in the asset pricing model,” which exactly matches the definition and role of betas/factor loadings in factor models.

5) Why other options are incorrect
- a: Idiosyncratic return is epsilon (residual), not beta.
- d: “exposures to all sources of systematic risks” is wrong because the model only includes selected factors; omitted systematic risks aren’t captured.
- e: Abnormal return is alpha, not beta.
- c: “None of the options” is false since b is correct.

6) Conclusion
- Therefore, the correct choice is b, which matches the provided answer.
