"they believe" can be used in 2 pattern

I have a pen that , they believe, is good

I have a pen that they believe to be good

the above patterns come from

they believe those students are good
they believe those students to be good.

in both patterns, "that" can be omitted.

both patterns in choice A and E are correct. but choice A is wrong because of meaning problem. explosion can not be a type, but belong to a type.

THE problem is using "one" before "they believe" ....why it do not use "that" after "one".....make sentence hard to detect which problem ...!

I may be wrong here, but i'm pretty certain all other answer choices but E lead to some sort of run-on issue. E comes off as a noun modifier.

I didn't see this at first, but it was the only thing that really made it clear why answers A to D are wrong.

A lot of folks are incorrectly stating that "that" is incorrect or redundant after "one." While there are certainly forms that allow us to skip "that," it's not incorrect here. We can say "one that they believe" or "one that they believe," depending on whether our meaning seems clear enough without the "that." "One" is a pronoun here, but it works just the way a noun does, and we can modify it the way we'd modify any noun.

A few examples:

I shared a poem that I believed was masterfully written. (Here, "that" helps to make it immediately clear that I believed something about the poem, rather than that I believed the poem itself. This is a common reason to include "that" or "who/whom.")
I shared several poems, including one that I believed was masterfully written.
I met many people that day, but there was one person I couldn't forget. ("That," or better yet, "whom," wouldn't be wrong here, but the meaning is 100% clear as is.)
Sitting across from me was a person I had believed to be dead.
Sitting across from me was a person whom I had believed was dead. (This second version feels clunkier. Although the "whom" makes it clear that I will be describing my belief, rather than saying I believed the person, the meaning was already fairly clear in the first version. I think some of the awkwardness comes from the switch from past perfect--had believed--to simple past--was. Although this switch is correct, it creates more work for the reader than the previous version, with its time-independent use of "to be.")

Dear EMPOWERgmatVerbal

Below is similar question from OG https://gmatclub.com/forum/the-world-wi ... 03470.html in which C is correct.
The World Wildlife Fund has declared that global warming, a phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.

(A) a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
(C) a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
(D) which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,
(E) which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,

By a similar logic, I think it should be (A) for the question: Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.

I am very confused.
Could you please shed some light on this?

Thank you very much!
Tracy

Use of that? one already works as pronoun, use of that is not required.
“Believe + to be” is correct construction
A B out
C that it is – one is already used as a pronoun therefore it here is redundant
D unidiomatic. That follows verb believe, this type of construction indicates start of new subject verb.
S+V THAT S+V However in this choice the construction is incorrect.
E CORRECT: they believe to be of a type
