Right option is (b) False

The best I can explain: A square wave is a periodic non-sinusoidal waveform with an uniform frequency, in which the amplitude alternates between a fixed maximum and minimum value. According to Fourier analysis, a square wave can be represented as an infinite sum of sinusoidal waves. A square wave consists of only components of odd integer harmonics.
