Verbal Ability - Sentence Correction - Discussion

In English, the form V + -ing is called a gerund if it serves as a noun. For example, the gerund form of "run" is "running". (I like cats, I like dogs, I like running). However, not all V + ing forms are gerunds--in "I am running", "running" is another verb.

1) If the to is part of a phrasal verb or verb + preposition combination:
A phrasal verb is something like " look forward to", " confess to", etc. In this case, the "to" is part of the verb itself. Some examples are:

I am looking forward to attending the party
I am committed to supporting the Linguistics proposal on Area51
2) If the to is part of an adjective + preposition combination:
For example:

A lot of women aren't accustomed to being treated so well!
I am opposed to increasing taxes.
These look similar to the examples above, but you can tell that a word like accustomed is an adjective in this case because there is a form of the verb to be. That is, you are an adjective.

3) If the to is part of a noun + preposition combination:

For example:
His addiction to gambling has caused a lot of stress for his family.
Her great dedication to teaching inspires her students.

ING used after TO but in rare cases, when ing comes that word work as a noun.

Yeah we can use in addition to enhance their reputation. But the second part of the sentence is in present continuous tense. So it is appropriate to use "in addition to enhancing".

"in addition, to enhance their reputations" sounds good but who knows what's right & what's wrong. : (.

'to' protects the verb written after it just like a model does so 'to enhancing' cannot be correct.

Sorry it's not the right one. After to how can one use ing. It can be option A.

Absolutely what @Pooja and @Satyansh said is correct. Because in addition to is the correct expression. And moreover I never listened the word like enhancing.

In addition to + verb + ing can be used.

Ex: My brother asked me if he might record the interview in addition to taking notes.

Friends - In addition to +verb+ing can be used.

Ex: 1 My brother asked me if he might record the interview in addition to taking notes.

Ex: 2 The cliff's sheer drop created a natural defense against any intruders in addition to providing a view that was breathtaking by day or night.

If is used as an infinitive then to + 1st form of the verb + is used.
