I think this is a poor-quality question and the explanation isn't clear enough, please elaborate. Not sure why but cannot be used to connect two independent clauses. Here is an example from MGMAT SC 6th edition. page no. 47.

Lin drove to work, but Guy rode his bike.
Here but is a conjunction connecting two independent clauses.

Of course "but" can be used to join two independent clauses. The erroneous sentence has been removed. However that does not affect the answer choice.
Thank you for pointing out.

the answer should be D. But is a conjunction and comma in front of but is acceptable.
Please help me understand this.

Just because , I got this one incorrect.

Does it work for all Conjunction. Could you explain GMATNinja Bunuel

Can you please explain the difference between "But with comma" & "But without it"?

The way I see this question is that 'If' implies a conditional sentence, 'if this happens then that happens' and therefore the second half of the sentence requires a Verb that implies a future action. 'May' is a Verb whilst 'Maybe' is a Noun or an Adverb and is not a Verb. 'May' also solidly implies a future action whilst 'Maybe' does not.

Furthermore, when two commas are used in a sentence then you should be able to ignore the fragment (the bit between the commas) as a test and see if the remainder (the main clause) still makes sense, and to make sense it requires a verb. This reinforces the choice between May and Maybe and the non-use of a comma.

I agree that Ans E is correct

I hope that helps

, but -> it is used when there are two independent clauses.

In this case Option E is correct as the clause after "but" is not independent.

This is the explanation that I needed. Nobody else seemed to have an answer for this. Thanks a lot!

punctuation is never tested in GMAT. Why the hell was this question made.

I understand the non-essential modifiers where phrase is separated by comma pair. But Option D is not that case. Why is comma before "but" wrong? This is still not clear to me. Request you to please assist.

In not only xxxxxx, but also xxxxxx - we use a comma but we havent used here. Whats the difference?

egmat

"A comma before the conjunction but is incorrect"

Despite having chosen the correct answer, I wanted to understand the use of commas. This explanation confused me. We have seen the commas before the but, but here it says as if it is wrong to use it.
and would that apply to the other coordinating conjunctions?

I think this is a poor-quality question and the explanation isn't clear enough, please elaborate.

I think this is a high-quality question and I agree with explanation.
