Answer 1

The correct answer is option C.

When testing the fertilizer on tomato farm, one patch is given with fertilizer and other is not given with the fertilizer then the effect can only be seen in the tomato farm that is having the fertilizer in it. The fertilizer here is dependent variable. The fertilized soil here will show the affect of fertilizer on tomato farm so it is experimental group.
