Solution
The question requires the ratio of the number of students enrolled in the B.Sc. program to the number of students enrolled in the B.Com. program.
B.Sc. Program Student Total
The total number of students in the B.Sc. program is determined to be 107.
B.Com. Program Student Total
The total number of students in the B.Com. program is determined to be 80.
Ratio Calculation
The ratio of B.Sc. students to B.Com. students is calculated as:
$ \frac{\text{Number of students in B.Sc.}}{\text{Number of students in B.Com.}} = \frac{107}{80} $
Thus, the ratio is 107:80.
This corresponds to Option C.
