Correct answer: b) l = 36º 05.8' N; L = 006º 00.6' W.
Why it is correct
Drawing the opposition line between Cape Trafalgar and Cape Spartel and intersecting it with the reciprocal bearing 220º from Barbate breakwater (36º 11.3′ N, 005º 55.3′ W) fixes the position at l = 36º 05.8′ N, L = 006º 00.6′ W.

- a) Does not match the intersection of the Trafalgar–Spartel opposition with Dv(Barbate) = 040º.
- c) Does not match the intersection of the Trafalgar–Spartel opposition with Dv(Barbate) = 040º.
- d) Does not match the intersection of the Trafalgar–Spartel opposition with Dv(Barbate) = 040º.
