Answer is: option2

Solution:

Critical points occur where \( f'(x) = 0 \), i.e., where the curve crosses the x-axis.
From the graph, there are four points where \( f'(x) \) crosses the x-axis.

To classify these critical points, we analyze the sign changes of \( f'(x) \):

1. First Crossing: \( f'(x) \) changes from positive to negative → Relative Maximum
2. Second Crossing: \( f'(x) \) changes from negative to positive → Relative Minimum
3. Third Crossing: \( f'(x) \) remains positive before and after → Not an extremum
4. Fourth Crossing: \( f'(x) \) changes from positive to negative → Relative Maximum

Two relative maxima

One relative minimum

The correct answer is - Two relative maxima and one relative minimum.
