Read each sentence to find out whether there is any grammatical error in it. The error, if any will be in one part of the sentence. The letter of that part is the answer. If there is no error, the answer is (D). (Ignore the errors of punctuation, if any).

A lot of travel delay is caused (A) / due to the inefficiency and lack of good management (B) / on behalf of the railways. (C) / No error. (D)

The correct answer is '3' i.e. on behalf of the railways is incorrect.

Key Points

• The error lies in part C, i.e., "on behalf of the railways."
• The phrase "on behalf of" is used to mean "in the interest of" or "as a representative of," which is not appropriate in this context.
• The correct phrase here should be "by the railways" to indicate the agent causing the inefficiency and lack of good management.

Correct sentence: A lot of travel delay is caused due to the inefficiency and lack of good management by the railways.

  • We are writing this letter on behalf of the employees.
• The phrase "by" is used to indicate the agent or cause of an action, as in:
