For parallelism ing verb form is needed. So A and D options are contender.
D: has correct use of idiom asssist with. And intended-meaning is same.
why D is wrong?
hello
deepverma, how are you?
I'm not an expert, but try to answer to your question
You are right down to //ism, we have A and D:
(A) throughout a real estate transaction by performing
(D) with a real estate transaction by accomplishing the performingI'm not good at idioms, maybe
"assist with" correct idiom in general, but any idiom usage is driven by the context and logic of the sentence.
Let's try to understand intended meaning of each choice:(A) A transaction-broker assists the buyer or seller or both throughout a real estate transaction by performing terms of any written or oral agreement, fully informing the parties, presenting all offers, and assisting the parties with any contracts, including the closing of the transaction, without being an agent or advocate for any of the parties.
1. A transaction-broker assists the buyer or seller or both (both here means buyer+seller)
2.
throughout a real estate transaction
(during the whole period of real estate transaction, from the beginning till the end )3. Assist by: performing terms of any written or oral agreement,
..................fully informing the parties,
..................presenting all offers, and
..................assisting the parties with any contracts,
4. including the closing of the transaction, without being an agent or advocate for any of the parties.
(A) clearly conveys intended meaning of the author
'throughout' - is absolutely fine here, in implies that transaction broker will assist clients all the time during a real estate transaction
(D) A transaction-broker assists the buyer or seller or both with a real estate transaction by accomplishing the performing terms of any written or oral agreement, fully informing the parties, presenting all offers, and assisting the parties with any contracts, including the closing of the transaction, without being an agent or advocate for any of the parties.
1. A transaction-broker assists the buyer or seller or both (both here means buyer+seller)
2.
with a real estate transaction
(implies that transaction-broker has own real estate transaction)3. Assist by: performing terms of any written or oral agreement,
..................fully informing the parties,
..................presenting all offers, and
..................assisting the parties with any contracts,
4. including the closing of the transaction, without being an agent or advocate for any of the parties.
Here 'with' has a little different meaning than 'throughout'.
Transaction-broker has own real estate transaction, and with this estate the broker assist buyer or seller or both
This is completely different logic.
Hence only (A) describe the author's thoughts correctly
