Directions: Read the sentence below to find out if there is any grammatical error in it. The error, if any, will be in one part of the sentence. Select the part with the error as your answer. If there is no error, select 'No Error'.

The regional authority, struggling with protests (A) / over the steep inflation rates, took (B) / a decisive action by reaching out to the central bank (C) / to an emergency assistance package (D) / No Error (E)

The correct answer is Option D.

Explanation:
Part (D) of the sentence contains a grammatical error due to the incorrect use of the preposition 'to' in the phrase 'to an emergency assistance package'.

The phrase 'reach out to [someone]' takes the preposition for when specifying the object or purpose being sought (i.e., 'reaching out to someone for something'). Therefore, the preposition 'to' should be replaced with 'for'.

Correct Sentence:
"The regional authority, struggling with protests over the steep inflation rates, took a decisive action by reaching out to the central bank for an emergency assistance package."
