ANS:A - True

Breakdown Voltage is the voltage at which the PN junction of a diode breaks down (hence the name "breakdown") accompanied with a sudden rise in current that flows in the reverse region. Basically, the diode will operate at reverse bias and as you continue to increase the REVERSE VOLTAGE which increases the reverse current you will reach the PEAK INVERSE VOLTAGE which is the maximum allowable voltage that the diode can take before it's PN junction would be damaged due to very high reverse current.
