Answer:

B) They are made up of particles that travel in a curved path when in motion.

Explanation:

We know that gas, being a state of matter, is made up of particles. John Dalton's solid-sphere model was proven to be incorrect by Ernest Rutherford's gold foil experiment.

These particles do NOT always move very slowly. There are multiple different factors that affect the speed of the particles such as temperature or concentration.
