Question

Arrange the following in meaningful sequence: A. Key B. Door C. Lock D. Room Choose the most appropriate answer from the options given below:

• A. \( \text{A, C, B, D} \)
• B. \( \text{D, C, A, B} \)
• C. \( \text{B, A, D, C} \)
• D. \( \text{C, B, D, A} \)

Hint:

\textbf{Meaningful Sequence Problems.} In these types of questions, the goal is to arrange a given set of items in a logical order based on a common process, relationship, or hierarchy. Think about the natural or typical progression involving these items.

Answer 1

The Correct Option is A

We need to arrange the given items (Key, Door, Lock, Room) in a logical and meaningful sequence. Let's consider the steps one would typically take to enter a room: (A) First, you would need a Key (A) to open the lock. (B) Next, you would use the key to open the Lock (C) on the door. (C) After unlocking, you would open the Door (B). (D) Finally, after opening the door, you can enter the Room (D). Therefore, the meaningful sequence is A, C, B, D. Let's check the other options:
D, C, A, B (Room, Lock, Key, Door): This sequence is illogical as you would need the key before the lock and the door before the room.
B, A, D, C (Door, Key, Room, Lock): This sequence is also illogical as you would need the key to open the lock on the door before entering the room.
C, B, D, A (Lock, Door, Room, Key): This sequence is illogical as you would need the key to open the lock. The only logical sequence is A, C, B, D.
