Answer:

(a) The temperature increases, the lid expands

Step-by-step explanation:

Running the lid under hot water will result in the transfer of heat from the water to the lid of the jar.

The heating up of the lid increases its temperature and the average kinetic energy of the molecules of the lid. Hence, the jar lid to expand and becomes easier to open.

The correct option is a.
