In the following question, sentences are given with a part in bold. The given phrase in bold may or may not contains an error. The options following can replace the incorrect phrase. The correct phrase that is to be replaced will be your answer. If the sentence is correct then select ‘No improvement required’ as your answer.

Every individual have rights which must never be taken away.

The correct option to replace the bold phrase is individual has rights which.

Step-by-step Explanation:

1. Subject-Verb Agreement: The subject of the sentence begins with the word "Every". In English grammar, determiners such as "Every" or "Each" are grammatically singular and must be followed by a singular noun and a singular verb.

2. Analyzing the Original Sentence: In the original phrase, "Every individual have rights...", the noun "individual" is singular, but the verb "have" is plural. This creates a subject-verb agreement error. The singular subject "Every individual" requires the singular verb "has".

3. Evaluating the Options:

- individuals has rights which: Incorrect, because "Every" should be followed by the singular noun "individual", not the plural noun "individuals". Additionally, "individuals" (plural) does not agree with "has" (singular).

- individual had rights that: Incorrect, because changing the tense to past tense ("had") alters the context of a general/universal truth expressed in the present tense.

- individual has rights which: Correct, as it correctly pairs the singular noun "individual" with the singular verb "has" in the present tense.

- individuals have rights that: Incorrect, because "Every" must be used with a singular noun ("individual"), not "individuals".

Therefore, replacing the bold phrase with "individual has rights which" makes the sentence grammatically correct: "Every individual has rights which must never be taken away."
