What is an Experiment?
An experiment may be defined as a complete procedure that must be carried out under controlled instances in order to reveal an unknown fact or law, to test or establish a hypothesis, or to illustrate valid evidence.
The complete experiment given above clearly demonstrates that the plant which grows in dim light attains a maximum height of 20.4 cm. as compared to bright or moderate light.
But the mass of the plant that grows in dim light is found to be lower than the bright light which is 2.1 g.
Therefore, the conclusion is that the plant grown in bright light will be shorter but have more mass than tomato plants grown in dim light. Thus, the correct option is C.
