Assertion(A): The maximum value of the function `f(x)=x^5`, `x in [-1,1]`,is attained at its critical point, x=0.
Reason(R):The maximum of a function can only occur at points where derivativeis zero.

B. Both (A) and (R) are true and (R) is not the correct explanation for (A)
C. (A) is true but (R) is false
D. (A) is false but (R) is true
