Directions: Four parts of the sentences given below have been underlined. Identify the part having an error. If no part has an error, mark (E).

One can only live without water (A) for about ten days (B) because almost 60 percent of (C) their body (D) is water. (E) No error

The error is in part (C). The pronoun 'their' is incorrect because the subject is 'One' (singular indefinite pronoun). The correct pronoun should be 'one's' to maintain consistency with the subject. The sentence states that a person can only survive without water for about ten days because most of their body consists of water.
