Answer:
D. Malnourishment
Step-by-step explanation:
Having an insufficient daily diet means that you get less than what is needed.
Agriculture is about things in the crops, farming categories, so it isn't this option.
Supply and demand refers to economics and that the price of an item gets raised if many people buy it, so it isn't this option.
Production is when you produce, or make materials, so it isn't this option.
Leaving us only with malnourishment. Also, nourishment means getting the right amount of food for health and other positive conditions, and the prefix mal means "bad", like the movie Maleficent. So, therefore this is the right answer.
