B Correct answer
Explanation

Let M be the number of men and W be the number of women. Since the number of married men equals the number of married women, 0.45M = 0.25W, so W = 1.8M. The total population is M + 1.8M = 2.8M, and the total married people is 0.45M + 0.25(1.8M) = 0.9M. The percentage is (0.9M / 2.8M) * 100 which is approximately 32.14%.
