B) The optimistic time estimate is an estimate of the maximum time an activity will require.

E) The most likely time estimate is an estimate of the maximum time an activity will require.

According to PERT, the expected time estimate is calculated as t = (a + 4m + b)/6, where a is the optimistic time estimate, m is the most likely time estimate, and b is the pessimistic time estimate. Option A is partially correct as the expected time is an estimate of the time an activity will require on average, considering all possible scenarios. Option B and D are incorrect as the optimistic time estimate is the estimate of the minimum time an activity will require and the pessimistic time estimate is an estimate of the maximum time an activity will require. Option E is incorrect as the most likely time estimate is an estimate of the most probable time an activity will require, not the maximum time.
