To meet the requirement that at least two students must be from each class, we can evaluate the options provided:
A) 5 freshmen and 7 sophomores
- This option has 5 freshmen and 7 sophomores. It satisfies the condition of at least 2 students from each class. (Valid)
B) 1 freshman and 11 sophomores
- This option has only 1 freshman, which does not satisfy the condition of at least 2 students from each class. (Invalid)
C) 6 freshmen and 4 sophomores
- This option has 6 freshmen and 4 sophomores. It satisfies the condition of at least 2 students from each class. (Valid)
D) 0 freshmen and 12 sophomores
- This option has 0 freshmen, which does not satisfy the condition of at least 2 students from each class. (Invalid)
Based on this evaluation, the viable solutions are A) 5 freshmen and 7 sophomores and C) 6 freshmen and 4 sophomores.
