Correct Answer: Option B — Come right to close the range then when on the range steer 093° T.

When outbound with a range astern (273°T) while steering 090°T and offset to one side, you must maneuver to close the range line before adjusting your heading to match the reciprocal track of 093°T to maintain the center of the channel.
