The basic building block of sequential logic circuit is-
Flip flop
A flip-flop is a bistable multivibrator, meaning it has two stable states (typically representing 0 and 1). A flip-flop can store one bit of binary information and retain that state until a trigger signal causes it to change. Therefore, the basic building block that gives sequential logic circuits their characteristic memory property is the flip-flop. Therefore, the correct answer is Flip flop.
