Why would the driver of a dog-sled team use the word "mush"? He wants the dogs to sit.

He wants to dogs to leap forward.

He wants the dogs to wait.

He wants the dogs to go.

D) He wants the dogs to go.

The website etymonline says the following:

mush (interj.)

command to sled dogs, 1897, first recorded 1862, as mouche, perhaps altered from French marchons! "advance!" (imperative of marcher "to march;" see march (v.))

So basically the driver is shouting "march!" (more or less) to the dogs for them to move forward. The "interj." means "interjection".
