Two Nav adjustments to the MDA/DA increase by how many feet?

Explanation:
Two independent navigation sources used for an approach require adding an altitude cushion to the MDA/DA. Each nav source contributes 100 feet, so with two sources you increase the MDA/DA by 200 feet. This provides protection against potential nav signal error or degradation, ensuring you don’t descend below safe altitude if one source misreads. The other options reflect different numbers of nav sources or increments, but in this scenario the total adjustment is 200 feet.
