The correct response is (A). The sentence is correct as written. The verb “is” agrees with its noun “political machine.” The verb form “becoming” is used appropriately as well.

If you chose (B), the infinitive form, although sometimes preferred on the GMAT, is not used correctly in this sentence. The participle is required.

If you chose (C), this choice may sound correct on its own, but placed back in the original sentence it reads “is becoming in danger a mere extension….” This answer choice does not make sense when placed in the underlined part of the sentence.

If you chose (D), the present perfect tense “has become” is not the correct verb form here. We use the present perfect to indicate that an action happened at an unspecified time before now. The simple present tense is all we need.

If you chose (E), the wording in this choice gives us a very unclear meaning, particularly when compared with choice (A). Since “has been” (i.e. ended at some point in the past) and “in danger of becoming a mere extension” (i.e. in the future) connote different time frames, the meaning of this choice is unclear. With (B), it’s clear that the machine is currently in danger of becoming (over time) an extension of big corporate agendas, as indicated by the reformer.
