Answer 1

C. such as

Step-by-step explanation:

That's the only one that fits into the sentence!

Answer 2

I think such as, because you are naming multiple symptoms. You are not comparing/contrasting, consequently is used in a sentence to state something as a result or therefore. Initially means at first, when used in a sentence. So, “such as” is the best choice.
