Question

Refer to the chairs shown below. Which of the following options is TRUE? 

• A. P is most stable in terms of centre of gravity and R is made of least number of visible parts
• B. S is made of least number of visible parts and Q is most stable in terms of centre of gravity
• C. P is most stable in terms of centre of gravity and S is made of least number of visible parts
• D. R is ergonomically comfortable and Q is most stable in terms of centre of gravity

Hint:

For stability questions, always look at the base width and centre of gravity. For part-count, note how many separate components are visible.

Answer 1

The Correct Option is C

Step 1: Compare stability (centre of gravity).
- Chair P: Wide base, heavy frame, low centre of gravity → most stable.
- Chair Q: Triangular seat on three legs → less stable.
- Chair R: Tall, thin legs, and narrow → least stable.
- Chair S: Curved wooden base, balance depends on design → not highly stable.
Step 2: Compare visible parts.
- Chair S: Made of a single bent wood + one seat → least number of visible parts.
- Chairs P, Q, R all have multiple visible elements (legs, seat, backrest).
Step 3: Eliminate incorrect options.
- (A): Wrong (R does not have least visible parts).
- (B): Wrong (Q is not the most stable).
- (D): Wrong (R is not ergonomically most comfortable).
- (C): Correct (P = most stable, S = least visible parts).
Final Answer: \[ \boxed{\text{C}} \]
