a. a cycle has begun in which personal computer users
b. a cycle for personal computer users has begun in which they
c. there is a cycle beginning for personal computer users
d. it is the beginning of a cycle for personal computer users
e. personal computer users are in the beginning of a cycle when they

The correct option is A

Explanation:

If we take a look at Subject/Verb agreement, pronoun agreements, and modifying phrases, we can see that option A tests OK for all the above tests.

In option B, using the word "they" is a wrong pronoun and does have a referent. Hence this option is also wrong.

Option C and D: The statement clearly states that users are replacing their PCs and hence using the prepositional phrase "beginning" with "for" makes this option invalid.

Option E: It is not personal computer users that are in the beginning of the cycle so this is a logically wrong.
