To calculate the weighted mean, we need to first calculate the total number of grade points earned by the student.

For History, the number of grade points earned = 3 (B grade) x 5 (credit hours) = 15
For Statistics, the number of grade points earned = 4 (A grade) x 4 (credit hours) = 16
For Spanish, the number of grade points earned = 2 (C grade) x 3 (credit hours) = 6
For English, the number of grade points earned = 2 (C grade) x 5 (credit hours) = 10

The total number of grade points earned = 15 + 16 + 6 + 10 = 47

The total number of credit hours for the semester = 5 + 4 + 3 + 5 = 17

The weighted mean grade for the semester = Total number of grade points earned / Total number of credit hours = 47/17 = 2.76

Therefore, the best choice is C, with the weighted mean grade for the semester being 2.76.
