Solution

The correct answer is 2) (A) and (D) Only

EXPLANATION:

• (A) Output of combinational circuits depends on the only current input. -
  • This statement is CORRECT. In combinational circuits, the output is solely determined by the current inputs, and there is no memory element involved.
• (B) Output of combinational circuit depends on the both current input and previous output. -
  • This statement is NOT CORRECT. The output of a combinational circuit does not depend on previous outputs, as it has no memory elements.
• (C) Output of sequential circuit depends on the current input. -
  • This statement is PARTIALLY CORRECT but INCOMPLETE. While the output of a sequential circuit does depend on the current input, it also depends on the previous state (or output).
• (D) Output of sequential circuit depends on both current input and previous output. -
  • This statement is CORRECT. In sequential circuits, the output depends on the current inputs as well as the previous outputs (or states), as these circuits have memory elements.
