Elisa 解答

I would break apart the sentence like this, so it is easier to understand. 

Computer has a number of applications.

 

Its use for helping design vehicles may be mentioned among a number of applications.

= Its use for helping design vehicles may be mentioned in a number of applications.

 

Subject: Its use for helping design vehicles.

Verb: may be mentioned.(passive voice)

 

倒裝句

Among a number of applications may be mentioned its use for helping design vehicles.

Or,

In a number of applications may be mentioned its use for helping design vehicles.

 

Here, "its" means "computer’s".

 

Computer’s use for helping design vehicles may be mentioned among its many applications.

 

If you want to use the phrase: “each of which”, you need to change the verb from passive to active voice.

 

Computer has a number of applications and each of the applications may mention its use for helping design vehicles.

 

= Computer has a number of applications, each of which may mention its use for helping design vehicles.

 

 

Here, "its" means "each of the application's"

 

So the correct answer is:
Computer has a number of applications, among which may be mentioned its use for helping design vehicles.

Or,

Computer has a number of applications, each of which may mention its use for helping design vehicles.

 

My explanation is from the stand point of grammar, not necessarily from the standpoint of logic.

What I am trying to say is if you truly want to use the phrase "each of which", you would need to change the verb from passive to active voice - just from the standpoint of grammar.

 

Computer has a number of applications, each of which "may mention" its use for helping design vehicles.

That is why answer (A) is accurate.
