A dynamic RAM consists of
A
6 Transistors
B
2 Transistors and 2 Capacitors
C
1 Transistor and 1 capacitor
D
None of These
Explanation: 

Detailed explanation-1: -Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are, of course, extremely small transistors and capacitors so that millions of them can fit on a single memory chip.

Detailed explanation-2: -Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology.

Detailed explanation-3: -Most all volatile memory is dynamic RAM because it uses only one transistor and one storage capacitor for each bit.

Detailed explanation-4: -The memory that uses one transistor and one capacitor as a basic memory unit is a DRAM. In a DRAM, a capacitor is used to store a bit of data along with a MOSFET (transfer device) which acts as a switch.
