Answer:

C. I&III

Step-by-step explanation:

I. In warmer temperature, particles move quicker allowing the sound to travel faster.TRUE

II.There is a wider space between particles in colder temperature allowing the sound to travel faster.FALSE. SOUND DOESN'T TRAVEL FAST IN COLDER TEMPERATURE. IF THE TEMPERATURE IS DECREASED, PARTICLES MOVE SLOWER, BECAUSE OF LESS ENERGY.

III.In colder temperatures, particles move slower making the sound travel slower. TRUE.

so the answer is I and III.
