I will go with "B".

The sentence is missing a verb. Need an "are" (plural, for plural quasarS) in there.

Look at it this way:
Quasars, ...., believed to be <something>.

It is incomplete. The part separated by commas is non-essential...it helps to just drop it to see the picture clearly.

This looks better: Quasars, ..., are believed to be <something>.

I'm just supporting the idea of sakali that the plural is needed here.

Even if you don't the meaning of the keyword "Quasars", you can find out the word "objects" in the

first sentence which explains in detail. In the second sentence, therfore, it should use "are".

This is just my strategy everytime I face some words I don't know of.
