As per my understanding , in option B pronoun they is clearly referring to personal computer users. But I have seen many posts where people have mentioned , that "they"
does not have clear referent.
Also if there is no pronoun issue why B is a better option than A .
Hello
akt715,
We hope this finds you well.
To answer your query, Option B suffers from pronoun ambiguity, as "they" can refer to "personal computer users" or "economists".
Further, the phrase "cycle for personal computer users" seems to imply that this cycle is limited to personal computer users, which is not the intended meaning; the intended meaning is that a cycle is taking place and personal computer users replacing their PC's is one part of it.
We hope this helps.
All the best!
