Choose any one of the following four responses:

1. If both assertion and reason are true and the reason is the correct explanation of the assertion.

2. If both assertion and reason are true but the reason is not the correct explanation of the assertion.

3. If the assertion is true but the reason is false.

4. If the assertion and reason both are false.

Assertion: The graph between P and Q is a straight line when P/Q is constant.

Reason: The straight-line graph means that P proportional to Q or P is equal to constant multiplied by Q.
