Ans B

the economic viability of the company depends on its ability for
- improving its efficiency
- capturing the market through innovative products.

There are two things that capture our attention in first glance -
ability for improving / ability to improve
Parallelism between improve and capture

A. its ability for improving its efficiency and capturing -INCORRECT
Ability for improving is incorrect

B. whether it can improve its efficiency and capture - CORRECT
The 'it' refers to company and improve and capture are parellel.

C. if it can improve its efficiency and capture - INCORRECT
If is conditional and usage of depends on If is incorrect.

D. whether or not it has the ability to improve its efficiency and can capture - INCORRECT
Introduces parallelism error by adding 'can' before capture.

E. the ability for it to improve its efficiency and capture - INCORRECT
Ability for it is incorrect idiom usage

I wonder how option B is answer as "whether" is not followed by "or".

Though in spoken language we often use "this depends on whether A will happen or not", the use of "or not" is redundant.

"this depends on whether A will happen" is clear and concise. You already know that this is a conditional and means "this depends on whether A will happen or A will not happen."
