b
The molecules of Rico’s potato are smaller than the molecules of Bree’s potato.
The molecules of Rico’s potato are smaller than the molecules of Bree’s potato.

c
The molecules of Bree’s potato are moving and the molecules of Rico’s potato are not moving.
The molecules of Bree’s potato are moving and the molecules of Rico’s potato are not moving.

d
The molecules of Bree’s potato are moving faster than the molecules of Rico’s potato.

Answer 1

The correct response is:

d The molecules of Bree’s potato are moving faster than the molecules of Rico’s potato.

This is because Bree's potato has been heated in the campfire, which increases the kinetic energy of its molecules, causing them to move faster. In contrast, Rico's potato, which has not been heated, has molecules that are moving slower.
