Best answer
Right answer is (c) 90°

The best I can explain: The radiation from a transmission line can be greatly improved by bending the transmission line conductors so that they are at a right angle to the transmission line. The magnetic fields no longer cancel and, in fact, aid one another. The electric field spreads out from conductor to conductor. The result is an antenna.
