The circle on the integral means that B(r) must be integrated

A. over a circle or a sphere.

B. along any closed line that you choose.

C. along the path of a closed physical conductor.

D.over the surface bounded by the current-carrying wire.

Im pretty sure its B but I just wanna be positive thank you.

"closed Path" which encloses current. B is the best answer. If you choose a closed path which encloses no current, then B is zero. On answer B, it would have been much better to word it "along any closed**path**that you choose". The word line, technically, cannot form a closed surface, and so the term "closed line"is somewhat without meaning.
