To calculate the distance the conduit needs to surpass, you have to add the values first, because the conduit will follow the ground and wall in a linear way. That gives us at least (4+5) feet to be covered, which discards options b and d.

And because we need a bit of extra length for the threading, the only logical available answer is a, 9 feet 4 inches.
