Answer:
false
Explanation:
Even though there is a bigger audience, you don't need to exclude information.
You need a slight stop there to collect your thoughts, especially when the next word is achromatopsia. That makes D wrong.
If you use B, " A medical condition that limits her vision" is not a sentence. So B shouldn't be the answer. Fragments are used by very good writers usually in fiction, and this statement is not part of something that is fictional.
A semicolon separates two equal clauses. You can think of it as meaning "and" or even "but" sometimes. You have the same problem with C as you do with B. So C is not correct.
