Step 1: Understanding the Concept:
This is a para-jumble question where sentences must be arranged in a logical, chronological sequence of events.
Step 2: Detailed Explanation:
Let's analyze the timeline of a typical examination:
1. The event starts with students arriving and entering the venue. So, Sentence B comes first.
2. After students are seated, the exam materials must be given to them. So, Sentence D (invigilator distributing papers) follows B.
3. Once they have the papers, the students can begin the task. So, Sentence C (writing answers) follows D.
4. The word "Finally" is a conclusive transition word, indicating the end of the process. Sentence A (results announced) is the final step.
The sequence is B $\rightarrow$ D $\rightarrow$ C $\rightarrow$ A.
Step 3: Final Answer:
The correct order is BDCA, which matches option (B).
