- ✓ The load must be swung as far as possible in both directionsCorrect

Why B is correct
46 CFR §28.885(c) specifies that after the proof load is lifted with the ship's normal tackle at the lowest practicable angle, it shall be swung as far as possible in both directions. This tests the full range of the gear under load.
