Which theory suggests that language originated from the sounds made by groups of people working together on difficult tasks?

Explanation

The Yo-he-ho Theory proposes that language developed from the collective vocalizations of people performing strenuous labor. In contrast, the Gesture Theory focuses on body movements, the Pooh-Pooh Theory attributes language to instinctive emotional sounds, and the Ding-Dong Theory links language to natural sound symbolism.
