Final answer:
Table tennis differs from other racquet sports mainly because it uses closed paddles instead of stringed racquets. The paddles result in different playing mechanics, and the sweet spot on tennis racquets minimizes arm jarring by efficiently transferring momentum with minimal vibration. The correct answer is option B.
Step-by-step explanation:
Table tennis is different from other racquet sports in several ways, but the correct answer to the question is B) It uses closed paddles instead of stringed racquets. Unlike tennis, badminton, or squash, where the racquets have strings, table tennis paddles are solid, usually made of wood, and covered with rubber on one or both sides.
The different structure of table tennis paddles contributes to unique playing dynamics compared to other racquet sports which use stringed racquets. Moreover, the ball in table tennis is much smaller and lighter, and the game is played on a hard table divided by a net, as opposed to a large court.
Regarding tennis racquets and their 'sweet spots,' when a ball hits this area, it results in minimal jarring of the player's arm due to optimal energy transfer.
