Final answer:
The synonym for "tug" is "pull," as it also signifies drawing something in a direction through force.
Step-by-step explanation:
The synonym for the word "tug" among the given options is pull. A tug is a gentle or slight version of a pull, generally used to describe the action of drawing something in a certain direction by exerting a force on it. The other options, tumble (to fall down), tumult (a loud, confused noise, especially one caused by a large mass of people), and tweak (to twist or pull something sharply) do not align with the meaning of tug as closely as pull does.
