In cadastral mapping, each map sheet is labeled with the location coordinates, then divided into sections, and further into four quadrants within that section. The four quadrants are labeled so that the bottom-right quadrant corresponds to the SE position and uses a specific quadrant letter in the standard notation. For the given coordinates, the sheet is CM 14°49'N-120°54'E, and the point falls in Section 1, in the bottom-right quadrant. That quadrant designation is the letter that completes the cadastral number after "sec. 1," giving CM 14°49'N-120°54'E sec. 1-C. This is why that option is the best choice: it correctly identifies both the section and the bottom-right quadrant of that section. The other options indicate different quadrants (or combine an incorrect quadrant with the section), which is why they don’t match the location.
