Analysis:

Frequency Components in Source Current:
The source current in a full-bridge diode rectifier contains frequency components that are multiples of the input frequency. In this case, the input frequency is 50 Hz.

Most Dominant Frequency Components:
The two most dominant frequency components in the source current are determined by the circuit elements connected to the rectifier. In this scenario, the series combination of finite resistance (R) and a very large inductance (L) will affect the frequency components of the source current.

Correct Answer:
The correct answer is option B, which states that the two most dominant frequency components in the source current are 50 Hz and 150 Hz. This is because the inductance L will introduce additional frequency components at multiples of the input frequency. Since L is very large, the 3rd harmonic (150 Hz) will be the most dominant component after the fundamental frequency (50 Hz).
Therefore, the source current in the full-bridge diode rectifier will have frequency components at 50 Hz and 150 Hz, making option B the correct choice.
