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.
That leaves us with A. That should be your answer.You need a pause of some kind and that pause is proved by the comma. The sentence is not a run on sentence just one in need of a pause in the middle.
Its the third one.

The part when he says that Fortano had done him a thousand wrongs
Explanation:
Tybalt is Juliet's cousin, originally, Tybalt wanted to duel Romeo instead. But since he and Juliet are married, he cannot fight Tybalt as he is basically his cousin-in-law, thus, Romeo rejects Tybalt's challenge. Mercutio finds this quite cowardly as a result he himself challenges Tybalt to fight.
The Supreme Court's decision in Plessy v. Ferguson was unconstitutional because since segregation laws did not provide equal protections or liberties to non-whites, the ruling was not consistent with the 14th Amendment.
In Plessy v. Ferguson's case in 1896, America's Supreme Court established that as long as there was equality, racially separated facilities were not unconstitutional. According to the Court, segregation did not discriminate.
But actually, the separate facilities granted to African Americans were infrequently equal. Normally they were far from being equal, or were completely inexistent.
Distribution of education budget in Florida, for example, was extremely different depending on the race: whereas white people counted on a budget of over 70 million dolars for their schools, libraries, and more, black people counted on a budget of less than 5 million. They teached and learned in churchs, huts, and shelters without bathrooms, water supply, desks or chalkboards.
This principle of "separate but equal" was only employed to reaffirm white majority supremacy over black minority, and was eventually abandoned in 1954.
