Assertion: If f(x) is a differentiable function, then the derivative of f(x) exists at every point in its domain.
Reason: The differentiability of a function guarantees the existence of its derivative at every point in its domain
Both assertion and reason are true, and the reason is a correct explanation of the assertion.
Both assertion and reason are true, but the reason is NOT a correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
