Amajor roadblock to writing is choosing a topic finding a quiet environment vocabulary length of the writing assignment

While all of these are arguably true (they all pose unique issues for writers), the first choice is the likely answer. choosing a topic tends to tie people up and, until a topic is secured, you can't even get started. not everyone needs a quiet environment to write and not everyone struggles with vocabulary or length, certainly. topics are something that all writers must choose.

I’m pretty sure the answer is B, but I would say you should also google parallelism examples online before you answer!
