The correct answer is B) Get clear of the ship. When abandoning ship, the immediate priority upon entering a life raft is to get as far away from the sinking vessel as possible. This is to avoid being pulled down or struck by the ship as it goes under. Once clear of the ship, other actions like drying the raft floor, accessing equipment, and addressing seasickness can be taken, but getting to a safe distance from the sinking ship is the critical first step. The other options, while important for survival, are not the immediate priority compared to distancing oneself from the sinking vessel. Inflating the raft (A), accessing the equipment pack (D), and administering seasickness medication (C) should come after establishing a safe position away from the ship.
