Given below are four sentences, out of which one sentence is grammatically correct. Choose the option which points out the grammatically correct sentence. If all sentences are incorrect. Choose ‘All sentences are incorrect’ as your answer.

Correct option is C

Below is an evaluation of the correctness of all the sentence in the options.
In statement (a), the error lies in the pronoun usage. “Perched” is a transitive verb and thus the action is attributed to the eagle, not the claws. The pronouns "they" and “themselves” are used to refer to the claws of the eagle, which is incorrect. The correct pronouns to use are "it" and “itself” because we are referring to the eagle, and as a singular noun. Therefore, the corrected sentence reads: "The claws of the eagle curved around the branch as it perched itself at the top of the large oak tree."
In statement (b), the error is the use of "farther" instead of "further." "Farther" typically refers to physical distance, while "further" is used to indicate additional or more extensive discussions in this context. Therefore, the correction involves replacing "farther" with "further." The corrected sentence is: "The committee voted to hold further discussions on an amendment to their mission statement."
In statement (c), there is no grammatical error. The sentence is correct as it is. The verb tense, subject-verb agreement, and sentence structure are accurate. The correction is not required.
In statement (d), The error in the sentence is the use of "side" instead of "sides." The word "side" should be in the plural form because it refers to multiple arguments or perspectives. Here's the corrected sentence:
"The news report provided an unbiased analysis of the political situation, presenting both sides of the argument fairly."
In this corrected version, "sides" is used to indicate that there are multiple viewpoints or arguments being considered in the analysis.
