The greatest internal force production by the leg muscles during a 100 m sprint typically occurs at 80 m. This phase of the sprint is critical because athletes reach high speeds and rely heavily on their leg muscles for maximal force to maintain and accelerate their speed towards the finish line.

At the beginning of the sprint (0 m to 10 m), while the athletes generate force to start, the overall speed is not yet high enough for maximal force production. Around 50 m, athletes are still in the acceleration phase, where force production is growing but not at its peak.

Hence, the choice "at 80 m" corresponds to a phase where runners have achieved near their top speed and are generating the greatest force to maintain that momentum, making it the correct answer.
