The following sentence is broken into four parts and two parts may contain an error in them. Find out the parts that contain the error.

Regarding the NRC case at Assam, (A) India's humanness will be tested (B) but it is also important off India (C) to consider the national interest. (D)

The correct answer is 4. In part A of the sentence, the preposition will be in and not at because Assam is a big place and we use 'in' with respect to big places. In part C of the sentence, the preposition will be for and not off because here the purpose of the test is focused on. Therefore, the correct sentence is: Regarding the NRC case in Assam, India's humanness will be tested but it is also important for India to consider the national interest.
