Answer:
Option "A" (the very first one) is an A Major scale.
Explanation:
A Major has three sharps in its key signature: F, C and G.
I suggest you learn your way around the key signatures, that way you'll be able to recognize any scale at any moment, it doesn't take long and it's very much worth the effort.
