Attempted by 92 students.

Show answer & explanation

Correct answer: C

Definition: for a single input output changes more than once.

Reason: For larger circuits there may be different routes to output. if each route has different delay, output may change more than once.

In combinational circuits, delays in logic gates (eg: NAND, NOR) may cause this hazard

In sequential circuits, delays by flipflops may cause this hazard

Hence answer is C
