Which mathematical base forms the underlying structural logic of standard computer memory capacity measurements? MCQ with Answer and Explanation

Question
Which mathematical base forms the underlying structural logic of standard computer memory capacity measurements?
A. Base 16 (Hexadecimal)
B. Base 10 (Decimal)
C. Base 8 (Octal)
D. Base 2 (Binary)
Answer: Option D
Solution (By JKSSB Mock Tests)
Computer systems process binary logic states (0 and 1). Thus, memory capacities naturally scale using powers of 2 (e.g., 2, 4, 8, 16, 32, 64).
