The incorrect element is the pronoun "them". The answer is (C) the pronoun "them" should be replaced by "him".
A pronoun is a word that is used to replace a noun in a sentence. The pronoun "them" is always used to refer to a plural noun, while the pronouns "him" and "her" are always used to refer to a singular noun. As the pronoun that comes after "stopped" is replacing the noun "man" in the sentence, the use of the pronoun "them" is incorrect because "man" is a singular noun. In that way, "them" must be replaced by "him", a pronoun that can be used to refer to a male person.
the answer is d. the only possible replacement is "ran fast" by "stopped it". the dog stopped it until his owner stopped it. we can develop a new sentence, adding new words, to use as an example of the modified sentence above: the dog stopped the other angry animal until his owner stopped it.
(a)their owner and it don't agree.
(b) until is time expression, instead is not.
(c) their is not in the sentence.
Option C: The pronoun “their” should be replaced by “its.”
Possessive Pronoun is a pronoun used to refer to the object to show ownership. For example: its, ours, yours, his, hers, mine are possessive pronouns.
In a sentence dog should be referred as 'its' and not 'his' or 'their'. So, the element which is wrong is that dog is referred as his. So, Option C mentions the portion that should be corrected. We cannot write 'their owner' in place of the dog, as per Option A. It is singular noun and not plural. Ran fast should not be replaced by stopped it as per option D.
C.The pronoun “them” should be replaced by the pronoun “him.”
The man sped down the road until a police officer stopped them. In this sentence there is not agreement between subject and object. Subject : The man, third person singular , and the object: them, third person plural.
The man sped down the road until a police officer stopped him. This sentence has agreement bewteen subject and object.
The The pronoun "his" should be replaced by "its."
In the sentence, "The dog ran fast until his owner stopped it," "his" should replaced by "its" since it should refer to the dog and not the owner.
Possessive Pronoun- this refers to things or objects that show ownership. Examples are: mine, ours, yours, his, hers, its and ours, etc.
The possessive pronoun "its" is used to show ownership of a non-human subject, So, this could refer to things or animals and other living things. This includes the dog.
A better sentence would be: "The dog ran fast until its owner stopped it."
