She requires that all of her children are to churn butter; resulting

Why is D not the answer please. D n E look good.

D inserts "are to" in between children and churn, that is unnecessary. Plus it changes "chore" to "requirement" which to my mind is a different meaning.

the trick here is that require can take both "to" and "that" in subjunctive mood.
we see that all options are with "that". this means only one thing - the verb that comes next must be in subjunctive form. only E correctly uses SM.

In subjunctive mood the verb used should be in plural form.

"Requires that" in my opinion should be " Require that".

Hi harshdev, there is some misunderstanding here. With the subject she, the verb will be requires (and not require).

The word requires triggers the subjunctive. So, the subjunctive structure will be after requires.

Could someone explain why the choice B is wrong, please?

Though this stem, is marked under easy, but really helps to understand the meaning of the sentence.

Here, the sentence deals with 2 events, casue and effects kind of structure.
1. She requires children to include churning butter into their daily core lists
2. Due to churning butter daily, children have gained impressive biceps

As you observe, below, sentence are twisted, which try to change meaning, either in the first part or second part of the sentence.
Errors, which needs to be check are: idioms, Intended meaning

A. She requires that all of her children are to churn butter; resulting from this daily chore, the children have formidable biceps.
Error:
1. "children are to churn butter" Why so complicated? when "chrun" itself is a verb, then you add "are" and "to", this makes sentence intended meaning error as well as reducant, while expressing meaning of it.
2. the difference between,
"as a result of" is preceded by phrase/clause
"resulting from" is preceded by noun or noun phrase,
here in option A,
"resulting form" does not exactly makes the sentence wrong, as it refers to noun 'daily chores',
but it fails to refer verb or action, "to chrun butter",which brings importance of formidable biceps.

B. She asks her children to churn butter; now the children have all become so formidable in their biceps.
Error:
1. The First part seems to be doing good, then you see "asks", question pops up ! What are you doing here?
"ask" is to look for an answer to a question by speaking
"require" is (obsolete) to ask (someone) for something; to request
2. other part of sentence is way too complicated! Why would "children become so formidable in their biceps" definately worng

C. She requires that all of her children churn must now butter; as a result of this daily chore, the children have formidable biceps.
Error:
1. children churn must now butter

D. She requires that all of her children are to churn butter; as a result of this daily requirement, the children have formidable biceps.
Error:
1. With same Error as in Option A,
Plus "daily requirement", which refer to needs or required, but only churn butter is not only the requirement, which results into formidable biceps, its one of the check list to perform in the daily chore.

E. She requires that all of her children churn butter; as a result of this daily chore, the children have formidable biceps - Correct
