a. Inverter
b. Rectifier
c. Chopper
d. Clamper

ANSWER: Rectifier
 
Rectification is the process of converting AC to DC & basically diode act as a rectifier. Rectifier is a circuit which comprises one or more diodes so as to convert ac voltage into pulsating dc voltage.
On the contrary, inverter plays a crucial role in converting dc to ac. Chopper performs the functioning of DC to DC conversion while clamper circuits introduces a DC level into an ac signal & usually referred as DC restorers.
