#3 is C, parallelogram is rotated -90° I think and moved down, so rotation and translation
#4 is B, I don't think the picture is showing how the fish loved, and it's facing a different way, so it's rotation
#5 is D, reflected over the x axis and translated to the right
#6 is B, reflected across the y axis
I hope these answers are correct, I'm answering right now at 3 am
