Answer:
I believe the correct answer would be B (my french is a bit rusty, but I am bilingual)
Step-by-step explanation:
The reason why is because "des eleves francais" is
1. plural therefore there would need to be multiple people
2. this is also masculin (if I remmeber right) so you would pick the image with the group of boys.
When taking french, you have to remember that all words can be classified as masculin or feminin, this one one of the main differences between english and french.
