Which hypothesis predicts the expected observations for glow sticks removed from containers of water at three temperatures?

a) The brightness of the glow sticks will be highest in the control temperature water, followed by the cold temperature water, and lowest in the hot temperature water after the 10-minute reaction period is complete.
b) The brightness of the glow sticks will be highest in the control temperature water, followed by the cold temperature water, and lowest in the hot temperature water after the 60-minute reaction period is complete.
c) The brightness of the glow sticks will be highest in the control temperature water, followed by the cold temperature water, and lowest in the hot temperature water after the glow sticks have been at the three temperatures for a total of 70 minutes and then allowed to continue to react and cool to room temperature for 30 minutes.
