OFFICIAL EXPLANATION





• Split #1 - noun/pronoun agreement

The word company is singular and takes the singular possessive pronoun its rather than their.

Options A and D incorrectly refer to the company's new safety regulations as their safety regulations.

Eliminate A and D

• Split #2 - the verb oversee must be followed by a noun

Jargon: many "transitive" verbs such as oversee must be followed by an object.**
A direct object answers this question: The company has created an advisory board to oversee WHAT?

Well, a what is a noun.

In option E, oversee is followed by as to how its new safety regulations are implemented.
→ as to how is not any kind of noun
→ if you are not sure, compare to option B: can you argue that option E is better than option B?
(Answer: no. Option B is more straightforward and more concise.)

In option C, oversee is followed by that its new safety regulations are implemented.
→ although that its new safety regulations are implemented is a noun clause, it does not answer the question "oversee WHAT?" very effectively or idiomatically.
Nor is this noun clause as good as the noun the implementation [of its new safety regulations] in option B.

Eliminate C and E.

The answer is B.

Other errors

→ Option A should use the implementation instead of the implementing.
A dedicated noun (implementation) is almost always better than an __ING noun (a gerund, a verbING).
The implementation is better than the implementing.

→ Option C should not use the word and after the comma
Several of which . . . is a relative clause that modifies the noun regulations.
Relative clauses should not be preceded by and; we do not place and between a noun (regulations) and its modifier (several of which . . .).

→ In option D, being implemented hints at changed meaning, suggesting that the advisory board is supposed to watch the implementation process as the regulations are being implemented.
Wrong.
The advisory board is supposed to ensure the implementation of the regulations.
The advisory board is not supposed to observe the implementation of the regulations.

Notes

Transitive verbs?
In order to express a complete thought, a transitive verb requires an object.
Wrong: I sent.
→ Send, like oversee, is a transitive verb. What did I send?
→ I sent a letter.

A transitive verb makes no sense without an object.

An intransitive verb is an action word that does not require an object and that makes no sense with an object.
He yawned.
Very few verbs are only intransitive.

Many verbs in English can be both.
She was singing. (intransitive)
She was singing a lullaby. (transitive)

Takeaway: if options contain verbs followed by different or differently phrased objects, check to see whether the objects are straightforward.

COMMENTS

himanshugoyal26 , welcome to SC Butler.

I like the fact that these answers contain variety.
Often, I must explain a concept in two or three different ways.
Too often I have no idea why, for example, explanation #2 "clicked" with the student.

One or a few of these posts will resonate with aspirants who read the thread.

In any event, I can see that almost everyone is trying to explain rather than merely label. Kudos to all.



**Noun clause?
→ In option C, that its new safety regulations are implemented is a noun clause (nominal clause, substantive clause)
Noun clauses can be confusing:
-- they typically begin with a relative pronoun (that, who) or relative adverb (what, where, when, why)
-- they always contain a verb, and thus are clauses, but
-- they are not "regular" clauses. They are "noun clauses." Although a noun clause contains a subject and verb, that whole clause acts as a noun in the larger sentence.
-- In other words, noun clauses act like nouns. They can be the subject of a sentence, for example, or the object of a verb.
Example: The boy taught his sister how to ride a bike.
What did the boy teach his sister?
What = how to ride a bike

This particular noun clause (that its new safety regulations are implemented) has subtle problems that you do not need to know as long as you compare (C) to (B).
