A. On the roof surface at least 10'' away from the wall.
B. In a hem.
C. In a termination bar.
D. 6'' above the roof surface.

The bottom of metal counter flashing on a tar & gravel roof intersecting a wall should be terminated in a termination bar to prevent water infiltration. The termination bar is a strip of metal secured at the termination point at the top of the flashing sequence.

Explanation:

In the construction industry, specifically in roofing, the intersection of a tar & gravel roof and a wall incorporates the use of metal counter flashing. The purpose of this counter flashing is to divert water from penetrating the construction. With respect to its position, the bottom of the metal counter flashing should be terminated in a termination bar.

The termination bar is a strip of metal used to secure the roofing material at the termination point. It is located at the top of the flashing sequence to provide an effective watershed and prevent passive water infiltration. Hence, option d, i.e., 'in a termination bar', is the most accurate answer to your question.
