I believe that the answer is B.) 2 - 5.
My reason being is because symmetry basically means 3-D , So you are asking how many sides can you see when looking through a jelly fish.
When looking through any jelly fish you will see 2-5 sides , 2-5 because there are four ( 4 ) , There is the front , the back and also both sides so it's four ( 4 ).
That was my reason for the answer I chose.
It would be D but you will not see at lease 5 sides to a jelly fish , why? = because they don't have 5 sides , most of them are square shaped or circular.
I really hope that this helped you out a lot.
