Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10'.
As per the official NBA rules, each basket ring must be securely attached to the backboard with its upper edge 10 feet (3.05 meters) above the playing surface, parallel to the floor, and equidistant from the vertical edges of the board.
This standard height has been used in professional basketball since the sport was invented by Dr. James Naismith in 1891. The rim has an inner diameter of 18 inches (45.72 cm) and is attached to a rectangular backboard measuring 6 feet by 3.5 feet. The 10-foot height ensures a balanced level of skill and athleticism between players of varying sizes. Even at youth and amateur levels, this measurement often remains the same to maintain consistency in play worldwide.
