Answer: book value.

**Explanation:** - **Option A (Correct):** Management's decisions directly impact a company's net income, which in turn directly influences its book value of equity. Book value is derived from the company's financial statements, which management controls. - **Option B (Incorrect):** Management actions can only indirectly affect the market value of equity. Market value reflects the collective expectations of investors regarding the company's future cash flows, which are influenced by external factors beyond management's direct control. - **Option C (Incorrect):** A company's intrinsic value is an estimate based on unpredictable future cash flows. While management can influence intrinsic value through strategic decisions, it does not have direct control over it.
