Answer & Explanation
Correct AnswerB. Lower PIV requirement per SCR

Quick Explanation

For the same DC output, a bridge converter subjects each SCR to a lower peak inverse voltage than a mid-point converter. This reduced PIV requirement is an important device-voltage-stress advantage of the bridge arrangement.
