B Correct answer
Explanation

EPROM (Erasable Programmable Read-Only Memory) is built using MOSFET technology with floating gates. The floating gate can trap charge to store data even without power. UV light erases the charge. Bipolar transistors, UJTs (Unijunction Transistors), and diodes are not used in EPROM manufacturing - MOSFETs are essential for the floating gate mechanism.
