Yes, "as" has several different uses. It can introduce a phrase or a clause. For example:

Clause
As I walked to school, I enjoyed the crisp morning air.

"I walked to school" is a clause because it contains a subject ("I") and a verb ("walked").

Phrase
As governor of the province, he had the power to pardon criminals.

The words "governor of the province" constitute a noun phrase.

Both "like" and "as" can also be used in comparisons.

In comparisons, "like" and "unlike" are used to compare two nouns.

Like strawberries, blueberries can be used to make jam.

I am as thrilled about the mission as they are.

(Also, notice the pronoun case - "I am as thrilled about the mission as them" would be incorrect.)

Hope this helps! Good luck!

Explanation why B is wrong - The conjunction 'as' may introduce a clause but
not a phrase

I know that 'Like' can't be used with a clause !

But, I remember reading that 'As' can introduce a clause or a phrase. Is that right ?

"Like" Is used to compare nouns/noun phrase whereas "As" is used to compare verbs/verb phrase. In choice B, "Brontës' and Brownings' idolization" is a noun phrase and therefore "As" cannot be used in this context.

Hope that helps !!
