Which of the following strokes in swimming does NOT start with a dive into the pool from outside?

Backstroke

The correct answer is Option (2) - Backstroke

Only backstroke starts in the water and not with a dive from the pool edge.

Butterfly, Breaststroke, and Freestyle (also called Front Crawl): These strokes all typically begin with a diving jump from the edge of the pool. The swimmer pushes off the wall with their feet and glides underwater for a short distance before surfacing and initiating the swimming motion.

Backstroke: This stroke is unique because the swimmer starts in the water on their back, holding onto the pool wall. They then push off the wall with their feet and begin swimming with a sculling motion of their arms. Their head remains above the water throughout the race.
