D. Clock is used to trigger the circuits to obtain outputs

Choose the correct answer from the options given below:





Solution

In a combinational circuit, output depends only on present inputs.

So, statement A is true.

Combinational circuits do not contain memory elements.

So, statement B is false.

They normally do not have feedback paths.

So, statement C is true.

Clock triggering is used in sequential circuits, not combinational circuits.

So, statement D is false.

Therefore, A and C only are correct.
