Answer 2

The error is in Option (d) 'increase every year'.

Finding and rectifying the error:

• In the question given, we must find out the error in it and also correct it.
• When we are given a sentence to spot the mistake, we must check if there is agreement among the parts of speech in it.
• Especially, the agreement between subject and verb must be looked into.
• Here the subject is 'the number of students'. The subject is singular because 'the students' is not the subject, but 'the number' is the subject.
• The plural noun 'students' takes plural verb 'appear'.
• A singular noun must take a singular verb. So 'the number' must take singular verb 'increases'. But here it is in plural form 'increase', which is wrong.
• Therefore the error is in Option (D) increase every year.
