Best answer
Correct option is (d) All of the mentioned

For explanation: Local maxima: a local maximum is a peak that is higher than each of its neighboring states, but lower than the global maximum.  Ridges: Ridges result in a sequence of local maxima that is very difficult for greedy algorithms to navigate. Plateaux: a plateau is an area of the state space landscape where the evaluation function is flat.
