Select the correctly punctuated sentence.

A) Depression, often a genetic disorder, can be safely treated with medication.
B) Depression, often a genetic disorder can be safely treated with medication.
C) Depression often a genetic disorder can be safely treated with medication.
I answered B

I disagree.

I meant to type A for my answer...fast fingers

Yes, A is right.

Actually, the correct answer is A. This sentence is correctly punctuated because it uses commas to set off the non-essential phrase "often a genetic disorder." Non-essential phrases provide information that is not necessary for the structure or meaning of the sentence. In this case, the phrase "often a genetic disorder" provides additional information about depression but can be removed without changing the main message of the sentence. By using commas to separate this phrase from the rest of the sentence, clarity and readability are improved.
