We do not require a verb so IS/ARE wrong;

IT IS starts another clause without a proper connector - drop

THINK OF X AS Y - is the correct usage but here X is missing; so drop OF AS

TO BE - CORRECT

IMO C

I chose B.

Candidates make statements that they think are true. >> They think statements are true

Vs

Candidates make statements that they think to be true. >> They think statements to be true.

First one sounds better to me.

Btw, what exactly is the difference between these two statements?

"Think to be" is unidiomatic. That's just the way it is.

"Think of as" or "Think is/are" is the correct usage.

In this example, we discard "is" due to S-V disagreement.
"Think of as" requires a noun as the end but we have "true" which is an adjective, so we discard "of as" option. That leaves us with "are" as the correct usage.

Cheers!

PS: Edit: Kalpita correctly pointed out that I had written "true" as a verb, while it is being used as an adjective (which it is mostly used for anyway, verb usage of true isn't common). Thanks kalpita.

A recent poll of elected officials suggests that candidates, when in the midst of a tough campaign, often make statements about an opponent that they may not think IS true

what is the attached subject for ARE ? I do not see one - am I missing something?

Poll ==> suggests; Candidates ==> make; THEY ==> may think

Statements is the subject.
Examples:...."Subject"......"verb"....

1. The "papers" that you asked for "are" here.
2. The "magazine" that you asked for "is" here.
If we remove the essential modifiers, we can see that the simplified sentences read.
1s. The papers are here.
2s. The magazine is here.

Examples are perfect. But how are the two clauses connected:

Candidates..often make statements ...ARE true.

We have two clauses (Candidates make Statements and Statements are true) - two independent clauses connected without a connector. Is it right?

eagleeye,

"true"" is acting as an adj here right & not as a verb.Rest of your explanation makes sense.

I think of him as my mentor (noun).

You are right. I meant "adjective" and wrote "verb". Cheers!
