Correct Answer: Option B — Contactors 'L', '1A', '2A' and '3A' pull in.

Selecting fourth point lower on a dynamic winch controller engages the lowering directional contactor ('L') alongside primary acceleration contactors ('1A', '2A', '3A') to progressively insert resistance and establish controlled lowering speeds under heavy deck loads.
