The peak value of the line voltage in case of 120° mode of operation of a three-phase bridge inverter is

(a) Vs/2

(b) 3Vs/2

(c) Vs/√2

(d) Vs

The question was asked in an international level competition.

This is a very interesting question from 3-Phase Bridge Inverters-3 in chapter Inverters of Power Electronics

Correct choice is (d) Vs

To elaborate: The peak value for 120° mode is Vs. The line voltage waveform is a sine wave with a peak value of Vs ( = supply voltage).
