The following sentence is broken into four parts and two parts may contain an error in them. Find out the combination which contains error. If the sentence is free from error, mark 'No error'.
The Convention on the Rights of Persons with Disabilities is a international (A) human rights treaty of the United Nations (B) intended to protect the rights (C) and dignity about persons with disabilities. (D) No error (E)
The given sentence is in the present tense.
In part A of the sentence, the article 'a' has been incorrectly used here as the first letter of the word 'international' is 'i', which is a vowel. So instead, it should be 'an'.
In part D of the sentence, the preposition 'about' has been incorrectly used as the sentence hints that the United Nations intended to protect the rights and dignity of persons with disabilities. Here the word 'protect' is a verb and it is doing something to the rights and dignity 'of' the persons with disabilities, not something 'about' it. So instead, it should be replaced with 'of'.
Hence, the error lies in the A & D parts of the sentence and the fourth option will be the correct answer in this regard.
