A. wrong construction 'was or was not'. Wrong time ('is' required)
B. 'whether or not' - right construction. 'Was' changed to 'is'. Than correctly terminated by 'is'. Right one - correct answer
C-E. 'but that' is awkward and ungrammatical.

What is OA?

IMO C.

The sentence is using the structure X but Y, we need to maintain parallelism between X and Y.
Here to maintain parallelism, we need to have a "that" after "but"
Researchers agreed that the study......but that more research....

I am not fan of 'whether or not', 'whether' is sufficient.

IMO:

- agreed that .. , but that -> shows parallelism.
Can someone confirm?

- Also in B 'is' is not necessary in end.
Is it?

I pick C.

Just a little query!! :)

The whole sentence is of past tense.

Why we are using "is" in below phrase
balloon angioplasty preceded by ultrasound is any better for heart attack patients ..

Why not "was"???

I derived the same answer, so I definitely think it's correct.

We already started new clause with conjunction 'but', so 'that' is absolutely redundant here!

Reseach was conducted in the past, but 'balloon angioplasty preceded by ultrasound' is better in the past and present.

Past: balloon angioplasty was better (until sth. new is invented)
Present: balloon angioplasty is better (still nothing is better)

what about the clauses when we use it with the conjunction 'and'? In that case, we look for parallelism "and that". Why in that case 'that' is not redundant?

IMO:
In D, "determined that" makes it in a subjunctive mood, so usage of 'was' is not correct.

None of the answer choices are perfect:

A. "Preceded with" is wrong. Should be "preceded by"
"was or was not" unidiomatic, wordy and awkward.
B. "Whether or not" is redundant and hence wrong on the GMAT. Whether should suffice.
"For determining" is wrong. It should be "to determine"
C. The use of "that" is avoidable but doesnt make the construction wrong. the best among the given options
D. "Preceded with" is wrong. Should be "preceded by"
E. "For determining" is wrong. It should be "to determine"
"is or is not" unidiomatic, wordy and awkward.

See this:

nice explanation!!
http://www.manhattangmat.com/forums/post1993.html#p1993
summary:
C is the best.
- 'but that' is correct for parallelism.
- to determine
- preceded by

Also something useful for "conjunction +that"

but here is conujction and not cordinating conjunction..so it is use to show contrat.....to work as coordinating conjunction it(but) must come after comma.....

"was or was not" is kind of awkward for me. So I choose B.
