This is a binomial probability problem where the number of trials n = 140, the number of successes k = 100, and the probability of success on a single trial p = 0.7. The binomial probability formula is P(X = k) = (nCk) * p^k * (1-p)^(n-k), where nCk is the combination of n items taken k at a time. Calculating this directly might be cumbersome, but using a binomial probability calculator or statistical software with these inputs will give a result close to 0.0669, making option C the correct choice.
