- B.
sequential circuit only
- C.

- D.
None of the above
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
