Correct option is A
Correct answer: (A) went on to become an important line of
Original sentence
The digital marketplace went on to become an importance line of business for the smartphone maker.
Why the highlighted part is incorrect
The highlighted part is “an importance line of”.
The error is in the word “importance”.
Reason:
Importance is a noun, while the sentence needs an adjective to describe the noun “line.”
Here, we need an adjective before “line of business.”
Correct adjective: important
Wrong:
an importance line
Correct:
an important line
Example:
She plays an important role in the company.
Here, important correctly describes the noun role.
Same rule applies here.
Correct sentence
The digital marketplace went on to become an important line of business for the smartphone maker.
Example
Online sales became an important source of income for the company.

So this structure is grammatically wrong.

This structure is not valid.
