Concept:
In sentence rearrangement questions, the objective is to arrange the given sentences in a logical and meaningful order. To do so, we identify:
• The introductory sentence
• The sequence of events
• Pronoun references
• Cause-and-effect relationships
A coherent paragraph should progress naturally from the beginning of an event to its conclusion.
Step 1: Identify the opening sentence.
Let us examine the sentences:
• (A) begins with “The teacher”
• (B) begins with “She”
• (C) introduces “Meena”
• (D) begins with “She”
The pronoun “She” used in sentences (B) and (D) must refer to someone already introduced.
Sentence (C) introduces the main character, Meena.
Therefore,
\[
\boxed{\text{Sentence (C) must come first}}
\]
Step 2: Determine what happens after the project is assigned.
Sentence (C) states:
Meena was assigned a project in the class.
After receiving the project, the natural next step is to work on it.
Sentence (B) states:
She worked hard to complete the project on time.
Thus,
\[
C \rightarrow B
\]
Step 3: Identify the next event.
Once the project has been completed, it can be presented.
Sentence (D) states:
She presented it confidently before everyone.
The word “it” refers to the project completed in Sentence (B).
Therefore,
\[
C \rightarrow B \rightarrow D
\]
Step 4: Determine the concluding sentence.
After Meena presents the project, the teacher evaluates her work.
Sentence (A) states:
The teacher appreciated her efforts.
This naturally serves as the conclusion.
Hence,
\[
C \rightarrow B \rightarrow D \rightarrow A
\]
Step 5: Match with the options.
The sequence obtained is:
\[
\boxed{C \rightarrow B \rightarrow D \rightarrow A}
\]
which corresponds to:
\[
\boxed{\text{Option (A)}}
\]
Conclusion:
The logical sequence of events is:
\[
\boxed{C \rightarrow B \rightarrow D \rightarrow A}
\]
Therefore, the correct answer is:
\[
\boxed{\text{Option (A)}}
\]
“Meena was assigned a project in the class. She worked hard to complete the project on time. She presented it confidently before everyone. The teacher appreciated her efforts.”
