DIRECTIONS: On the basis of following diagram/ picture answer the questions given below. A pupil did an experiment to investigate the loss of water by plants. The apparatus that she used is shown in the diagram. The rate at which the water level fell (water loss) in the measuring cylinder was measured at regular time intervals, (i) for a plant without the hair dryer, (ii) for a plant with a hair dryer blowing warm air over the leaves, and (iii) fora plant with a hair dryer blowing cool air over the leaves. The pupil used the data to draw the graph shown. Match up the three graphs with their corresponding conditions

A) A = warm air, B = normal, C = cool air

B) A = normal, B = cool air, C = warm air

C) A = cool air, B = normal, C = warm air

D) A = normal, B = warm air, C = cool air
