If the unplayable ball is in a bunker, the player may proceed under Clause a, b or c. If he elects to proceed under Clause b or c, a ball must be dropped in the bunker.
In normal circumstances, your absolutely right, but.....
I believe the relief is being taken from the water, not the bunker so he can drop behind the bunker as far back as he/she wants
