Proponents of artificial intelligence

[sk8ternite]

Proponents of artificial intelligence say they will be able to make computers that can understand English and other human languages, recognize objects, and reason as an expert does—computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these.

(A) as an expert does—computers that will be used to diagnose equipment
breakdowns, deciding whether to authorize a loan, or other purposes such as these
(B) as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan
(C) like an expert—computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan
(D) like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized
(E) like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like

answer is c. I don't understand the reasoning.

IMO C is best because:

(A) as an expert does—computers that will be used to diagnose equipment
breakdowns, deciding whether to authorize a loan, or other purposes such as these
Parallelism issue.....diagnose....deciding...or other purposes.

(B) as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan
which no immediately preceding noun.

(C) like an expert—computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan
correct.

(D) like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized
like is not used for giving examples. Also should is used to give order in GMAT. whether or not required. whether is sufficient.

(E) like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like
diagnose not parallel to deciding...

This is a 3:2 split.. as an expert does or like an expert..

We are comparing a computer to an expert and so comparison should be between computer and an expert and not what an expert can do.
Based upon this we can eliminate A and B

C] Perfect

d] Many errors.. use of like in place of such as. whether or not is redundant, just using whether would suffice.. awkward structure

e] again multiple errors

[spoiler]make computers that can reason as an expert does vs like an expert - which is correct. For me both possible. Pls suggest[/spoiler]
