A.

46

B.

44

C.

45

D.

47

Correct option is B

Given:  Mona ranked is 9th from the top and 36th from the bottom in a class. 
Formula: Total students = Rank from the top + Rank from the bottom - 1
Mona's rank from the top = 9th
Mona's rank from the bottom = 36th
Apply the formula:
Total students = 9 + 36 – 1 = 44
Thus, the total number of students in the class is 44.
Thus, the correct option is (b) 44.
