Question 11.

A: Sentinel robots are just fiction that is mentioned in the passage to introduce the new wave of development that has taken place. Option A is eliminated.

B: The author has introduced X-men as an example only. His arguments are not related to the creation of X-men in any way. Option B can be eliminated.

C: .....but some of them could one day swim through our bloodstream to heal us.

Throughout the passage, the author is trying to highlight the positives of the new robots. Hence, a direct extension of the argument would be the robots healing us at a microscopic level, as is hinted in the above excerpt. Option C is the answer.

D: Option D, though not entirely incorrect, is not a direct extension of the arguments presented in the passage. Unlike Option C, D has not been hinted at in the passage. Hence, it can be eliminated too.
