Answer: (c) seed type

Explanation:

An independent variable is the one which can be altered or manually manipulated in an experiment. The effect of such manipulation can be examined on the dependent variable of the experiment. The dependent variable cannot be manipulated in an experiment instead it is the outcome of the experiment.
