Eh, B and C are obvious, but A is the real gem here. 3dB power drop, that's the key definition of the main lobe!

I'm going with A, B, and C. Anything that improves directionality and anti-interference is a win in my book.

Haha, D can't be right! The terminal can't just receive the signal within the half-power angle, that would be too limiting.
