In the following question, a sentence is given with a few highlighted words that may be incorrectly placed. Rearrange these words to form a sentence that is both grammatically correct and contextually meaningful. Then, choose the option that represents the correct sequence of the highlighted words.

Heavy rainfall (A) caused delays in several airport (B) departing from the city flights (C).

The correct option is ACB.

Step-by-step Explanation:

1. Analyze the original sentence:
"Heavy rainfall (A) caused delays in several airport (B) departing from the city flights (C)."

2. Identify the highlighted words and their parts of speech:
- (A) caused: Verb (past tense)
- (B) airport: Noun (singular)
- (C) flights: Noun (plural)

3. Evaluate the placement and grammatical correctness:
- The phrase "several airport" is grammatically incorrect because the determiner "several" must be followed by a plural noun. Replacing "airport" (B) with the plural noun "flights" (C) corrects this, forming the phrase "several flights".
- The phrase "departing from the city flights" is contextually incorrect because flights depart from an airport, not from other flights. Replacing "flights" (C) with "airport" (B) corrects this, forming the phrase "departing from the city airport".
- The verb "caused" (A) is already in the correct position, linking the subject "Heavy rainfall" to the object "delays".

4. Formulate the corrected sentence:
"Heavy rainfall caused (A) delays in several flights (C) departing from the city airport (B)."

Therefore, the words must be rearranged in the sequence ACB to make the sentence grammatically correct and contextually meaningful.
