Option A is right. Because it crosses zero at the angle of 45 degrees. But B is cross after 60 degrees.

I support for the option A because the one which crosses zero cross over will lead the other one.

Option A is correct, Consider the Zero Crossing concept, then you will get it.

Answer B is the correct option because wave b is at 60 and the wave is at 45.

Option A is right because A reaches to 0 before B at 15 degrees.
