Correct Usage of "Both" with Plural Nouns
Step 1: Understanding the Rule
The phrase "their hands" refers to two hands, so we use "both."
Step 2: Analyzing Incorrect Options
- Every: Used with singular countable nouns (e.g., "Every student was present.").
- A: Grammatically incorrect in this context.
- Each: Used for individual items, but "both" is correct when referring to two things together.
Step 3: Applying the Rule
The correct sentence should be:
"They raised both their hands."
Final Answer:
Thus, the correct answer is "both" (Option A).
