The answer is A.

A -- nothing wrong grammatically
B -- growing is a gerund and it out of place, and 'as big as 30 feet long' is awkward since 'big' is not a good word to describe how long something can get. It should be 'as long as 30 feet'.
C -- growing and being are both gerunds and out of place
D -- same problem with 'as big as 30 ft long'
E -- 'it' is redundant
