The cumulative probability distribution at a given point is the sum of probabilities for all outcomes up to and including that point. Without specific details of the distribution, it's impossible to accurately determine the value. However, if this is based on a known distribution or example where P(X ≤ 2) = 0.80, then C would be correct.
