Farheen soaked some bean seeds in water overnight. Next morning she drained the water and kept the seeds moist till they started germinating. She boiled half of the seeds and then kept the germinating seeds in one thermos flask (X) and the boiled seeds in another thermos flask (Y). She covered the mouths of both flasks with moist cotton wool. Then she inserted thermometers in both flasks and kept the flasks as shown in the figure.


What would be her observation?

A Temperature of flask X increases because it has photosynthesising seeds.
B Temperature of flask X increases because it has respiring seeds.
C Temperature of flask Y increases because it has boiled seeds.
D Both (B) and (C)
