As the temperature increases, average kinetic energy of molecules increases. With increase in temperature at constant volume, the pressure -  

1. Increases

2. Decreases

3. Remains same

4. Becomes half

HINT: Follow Gay - Lussac's Law  concept.

Explanation:

As the temperature increases, average kinetic energy of gaseous molecule increases. From Gay-Lussac's law, at constant volume, as the temperature is increased, pressure increases.
