The correct option is A
True

We know that strictly increasing function always increases. Let's look at the graph -

It is obvious from the graph that it’ll have the maximum value at the point where it is ending. In the interval of [a,b] it’ll have the maximum value at x = b. The point which has greatest value in the interval is called as global maximum so x = b will be the global maximum.
