What effect does increased weight have on a multirotor's descent and flare-like slowdown before landing?

• A.It descends more slowly with no extra power needed
• B.More power and anticipation are needed to arrest the greater downward momentum
• C.Weight does not affect descent because gravity assists the motors

Why

A heavier aircraft builds more downward momentum in a descent. Arresting that descent takes more thrust and must be started earlier to avoid a hard touchdown.
