Maren Hodge · Answer 1

The correct answer is D, Amount of sunshine.

Indeed, fertilizer may or may not increase yields depending on many complex factors such as humidity, dryness, chemical balance, method of dispersion etc. However, it is an established biological principle that plants fare better with sunlight and in the absence of sunlight they yield less produce, whether they are fertilized or not.
