Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 3 i.e. 40 millimeters.
According to the official rules of the International Table Tennis Federation (ITTF), a standard table tennis ball must have a diameter of 40 mm. Historically, the sport used 38 mm balls, but the size was increased following the 2000 Sydney Olympics to slow down the speed of the game and make it more viewer-friendly for television. The ball must also weigh exactly 2.7 grams and be made of celluloid or similar plastic material to ensure consistent bounce and flight.
