B Correct answer
Explanation

The total number of students is 150 + 100 = 250. The total number of students who passed is (0.84 * 150) + (0.77 * 100) = 126 + 77 = 203. The average pass rate is (203 / 250) * 100 = 81.2%.

AI explanation

The number of passing 1st year students is 84 percent of 150, which equals 126. The number of passing 2nd year students is 77 percent of 100, which equals 77. The total number of passing students is 126 plus 77, giving 203. The average pass rate is 203 divided by 250, resulting in 81.2 percent.
