Oh yeah i got it. Thanks. As per your question you made a mistake when you confused what caused development. This is generation, not machines. Look at modifier in underlined part and you will see that "generation" lacks verbs. Since "generation" is singular we need "is". Hence A,D and E are out. Between B and C. "Capable for" is wrong idiom. Hence C is correct. Hope it helps

abhimahna · Answer

I think you are missing the correct subject of the sentence.

A new generation   of sophisticated copy machines, capable of unprecedented detail and accuracy,   are prompting  the development of more complex currency designs to prevent counterfeiting.

We have "A new generation" as the subject, so it will take singluar verb "is". Thus, A, D and E are incorrect.

Now, Capable of is the right idiom which is correct only in C. Hence the answer.

Prathit · Answer

In this question, i understand why option C is correct. My question is, if we replace 'is' in place of 'are' in the option E, will it become a better choice than option C?

surbhipuri · Answer

In the above sentence the subject is a new generation not a not  A new generation of sophisticated copy machines 
Prepositional phrases are never part of the subject .Therefore it should be followed by singular verb "is" rather than are.
So only B and C are left .Here capable of is correct idiom not capable for.

A new generation of sophisticated copy machines, capable of unprecedented detail and accuracy, are prompting the development of more complex currency designs to prevent counterfeiting. 
a. sophisticated copy machines, capable of unprecedented detail and accuracy, are
b. sophisticated copy machines, capable for unprecedented detail and accuracy, is 
c. sophisticated copy machines, capable of unprecedented detail and accuracy, is 
d. sophisticated copy machines, capable for unprecedented detail and accuracy, are
e. sophisticated copy machines that are capable of unprecedented detail and accuracy are

My two cents -

A new Generation can't be the subject of the sentence because it does not make sense with the verb "are prompting". We should take "A new generation of sophisticated copy machines" as the subject. Whenever a phrase is a subject it is always singular. So A,D and E are incorrect.

B - Capable for is not idimatic
C - correct answer.

A new generation of sophisticated copy machines, capable of unprecedented detail and accuracy, are prompting the development of more complex currency designs to prevent counterfeiting.

a. sophisticated copy machines, capable of unprecedented detail and accuracy, are
- "are" is the INCORRECT verb because its plural. The subject is "GENERATION" = SINGULAR. Therefore, "is" is the appropriate choice

b. sophisticated copy machines, capable for unprecedented detail and accuracy, is
- "capable for" is an INCORRECT IDIOM. Correct idiom = "capable of"

c. sophisticated copy machines, capable of unprecedented detail and accuracy, is
- correct as is

d. sophisticated copy machines, capable for unprecedented detail and accuracy, are
- same as "A". also, same as "B"

e. sophisticated copy machines that are capable of unprecedented detail and accuracy are
- same as "A". also, wordier than need be because of "that".

Kudos please if you find this helpful

KAPLAN OFFICIAL EXPLANATION:

C

Like many GMAT sentences, this one is complex, but contains a predictable, relatively simple error. If you familiarize yourself with commonly tested errors and learn how to correct them, sentence corrections can be a breeze. As soon as you see a subject (“a genera- tion”) followed by a long phrase (“of sophisticated copy machines capable of unprecedented detail and accuracy”) beware! GMAT sentence corrections often contain subjects and verbs that are separated. The verb “are” here is separated from the subject “genera- tion,” but they still need to agree. Generation is sin- gular, so it should be “a new generation IS prompt- ing.” In(B), it’s unidiomatic to say “capable for.” You need to say “capable of” detail.

Official Explanation

Read the Original Sentence Carefully, Looking for Errors:

As soon as you see a subject ("a generation") followed by a long phrase ("of sophisticated copy machines capable of unprecedented detail and accuracy"), beware! GMAT Sentence Correction questions often try to distract you from subject-verb agreement problems by putting a lot of words between the subject and verb. Here, the singular subject "generation" requires the singular verb "is." Eliminate (A). In (B), it's unidiomatic to say "capable for." You need to say "capable of" detail.

Scan and Group the Answer Choices:

A scan of the ends of the answer choices shows a 3-2 split between "are" and "is." Only (B) and (C) use the correct singular verb.

Eliminate Wrong Answer Choices:

Along with (A), eliminate (D) and (E) because they end with the plural "are." Now look at the remaining two choices more closely.

"Capable for" in (B) is unidiomatic. You are capable of earning a high score on the GMAT, not capable for earning a high score. (C) uses the idiomatically correct "capable of" and the correct singular verb "is," and this is the right answer.

TAKEAWAY: When a verb is the first or last word underlined, pay special attention to whether it matches its subject in number and whether it is the correct tense.
