The Correct Option is B

Solution and Explanation

This question tests the correct use of clauses when expressing reasons. The sentence given is: "The reason for (a)/his failure is because (b)/he did not work hard. (c)/No error (d)". Let us analyze the statement and options:

  1. The clause in part (a) introduces the subject and the general idea of what is being discussed: "The reason for his failure". This part of the sentence is correctly structured, and there is no error here.
  2. Part (b) begins with "is because". In English grammar, it is tautological (redundant) to use "the reason is because". The correct phrasing should be either "The reason...is that..." or "He failed because...". Therefore, the error lies in part (b), where "is because" should be replaced with "is that".
  3. Part (c) "he did not work hard" logically completes the sentence by stating the reason for failure. There is no error in this part.

To correct the sentence: "The reason for his failure is that he did not work hard."

Hence, the option containing the error is (b).
