In each of the following questions, a sentence with four highlighted words has been given. One of these highlighted words may or may not have been used unnecessarily in the given sentences. You are required to choose the word that is redundant and gives a superfluous meaning. If all of the highlighted words are essential for the contextual meaning of the sentence, then choose option (e) as your answer choice.

The central government has re-issued an ordinance (A) forming an air quality control (B) commission, which worries concern (C) about the procedure of re-issuing ordinances without getting them ratified (D) by the Parliament.

The correct option is C.

Let us analyze the sentence step-by-step to find the redundant word:
"The central government has re-issued an ordinance (A) forming an air quality control (B) commission, which worries concern (C) about the procedure of re-issuing ordinances without getting them ratified (D) by the Parliament."

1. "ordinance (A)": Correctly refers to an official order or law. It is contextually necessary.
2. "control (B)": Properly describes the type of commission (an air quality control commission). It is contextually necessary.
3. "concern (C)": Looking at the clause "which worries concern...", we see a duplication of meaning. Both the verb "worries" and the noun/verb "concern" convey the same idea of causing anxiety or being of interest. Furthermore, grammatically, "worries concern" does not make sense in this context. The intended meaning is either "which worries those who care about..." or "which raises concerns about...". Thus, the word concern is redundant and grammatically incorrect when used next to "worries".
4. "ratified (D)": Correctly refers to making an agreement or treaty officially valid by voting for or signing it. It is contextually necessary.

Therefore, the word concern (C) is redundant and should be removed or replaced to make the sentence grammatically correct and contextually meaningful.
