Correct Answer: C
Comprehensive and Detailed In-Depth Explanation:
Mark-to-market (MtM) involves valuing positions at current market prices daily, primarily for the trading book (e.g., securities, derivatives). Option C-obtaining and verifying market prices for trading book instruments-is the core MtM activity under Basel III's market risk rules. Option A applies to the banking book (not typically MtM), Option B describes settlement, and Option D is a profitability analysis, not MtM.
