To calculate the probability of completing the project in 24 or fewer weeks, we need to add up the probabilities for all activities that have a total time of 24 weeks or less. These activities are:

A + B + D + E + G + H + I + K + L + M + N

The sum of their probabilities is 68%, which falls under the range of "greater than 65% but less than or equal to 75%". Therefore, the best choice is C.
