Your examples don't match what's going on in the sentence and highlight to me why you're confused. To see that let's compare your sample sentences to a pared down version of the original sentence:
Eg1. Jim cleaned the bedroom and wiped the floor-CORRECT
Eg2. Jim cleaned the bedroom, and wiped the floor-INCORRECT
...The most extensively used method has been to form, and to lay
In the problem the comma can appear before the and so long as a full independent clause is formed. In this case, "to form" and "to lay" are objects of "has been" and thus will be part of an independent clause no matter what because one clause ends after "to form" and the ", and" shows us another possible object of "has been."
You can read more about the use of ", and" vs. just "and" in this post:
comma-and-vs-and-t11444.htmlEither way, I want to point out that the ", and" vs. "and" wasn't a split in play here. Remember, there's no use in "tilting at windmills" in these problems. The GMAT isn't going to put answer choices on the test that are obviously wrong so there isn't a reason to try to look into a problem to find a "more correct" of writing the answer choice. I'm not accusing you of doing so here but just want to remind you as well as everyone else reading this post of that fact :)
Thanks,
Chris
thanks for your answer, but i am still confused about independent clause after ", and". I cannot accept that "to lay" after ", and " is a independent clause because it's not a complete sentence. Can you give some information more detail about this question on independent clause after ", and"
Instructors please correct me If Im wrong.
In this construction the linking verb applies to both part of the parallelism i.e if the 2 nd part doesn't contain a complete verb form then the "helping verb" applies to the 2 nd part
For example :
jake has worked here for many years and won many awards
here "has" the linking verb applies to the 2nd part
Full version would be
jake has worked here for many years and has won many awards
One more from Real GMAT question
According to some analysts, the gains in the stock market reflect growing confidence that the economy
will avoid the recession that many had feared earlier in the year and
instead come in for a "soft landing"
here in the 2nd part "come" alone cannot act as a verb and the 1st part has a helping verb too "will" hence the "will" is understood / implied in the 2nd part
According to some analysts, the gains in the stock market reflect growing confidence that the economy

instead WILL come in for a "soft landing"
But if we have a complete verb form in the 2nd part the helping verb does not apply
The company has announced its profits and is in state of bankruptcy
"has" does not apply to the 2 nd part
The company reduced itself into smaller Units and has been working on a plan to develop more such units.
"has" does not apply to the 1st part
Similarly for the question under discussion -
The method has been "to form" and has been "to lay"
Instructors please correct me If WRONG.Cheers
