In the following sentence, some segments of the sentence are underlined. Your task is to identify that underlined segment of the sentence, which contains the mistake that needs to be corrected.

Explanation

The correct answer is option B: 'Is the factor'. In this case, the subject is plural ('three factors'), which requires the verb to be plural as well. Therefore, the correct phrase should be 'are the factors'. Options A, C, D, and E do not contain errors related to subject-verb agreement. 'Along with' does not influence the subject, 'Take' and 'Towards' are both used correctly, and 'No error' is incorrect because there is a clear mistake in the sentence structure.
