      A Pressure decreases Correct Answer Incorrect Answer
      B Pressure increases Correct Answer Incorrect Answer
      C Volume increases Correct Answer Incorrect Answer
      D Volume decreases Correct Answer Incorrect Answer

      Solution

      When the temperature of a gas is increased at constant volume, the kinetic energy of the gas molecules increases.   This leads to more frequent and forceful collisions with the walls of the container.   As a result, the pressure of the gas increases according to Gay Lussac's law.
