Which of the following is NOT a fat soluble vitamin?
Vitamin D
Vitamin C
Vitamin E
Vitamin A
Vitamin K

A. Vitamin D: Vitamin D is fat-soluble and is absorbed along with dietary fats. It is stored in the liver and adipose tissue and plays a key role in calcium and phosphorus regulation.
B. Vitamin C: Vitamin C is water-soluble, not fat-soluble. It dissolves in water, is not stored extensively in the body, and must be obtained regularly through the diet. Its main functions include collagen synthesis and antioxidant protection.
C. Vitamin E: Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. It is stored in adipose tissue and the liver for long-term use.
D. Vitamin A: Vitamin A is fat-soluble and essential for vision, immune function, and epithelial tissue health. It is stored in the liver and released as needed.
E. Vitamin K: Vitamin K is fat-soluble and plays a critical role in blood clotting and bone metabolism. It is absorbed with dietary fats and stored in the liver.

C. Energy: Energy is a general term and does not differentiate between stored and active forms.
D. Potential: Potential energy is stored energy that has the capacity to do work in the future, such as chemical energy in bonds, a stretched spring, or gravitational energy in elevated objects.
Correct Answer is C
Explanation
A. The nervous system causing all living things to sometimes experience anger: Excitability or responsiveness is not related to emotions such as anger. It is a fundamental property of cells and organisms that allows them to detect and respond to stimuli.
B. Indigestible food residues stimulating the excretory system: This describes elimination, a separate functional characteristic of life. Responsiveness is about detecting and reacting to internal or external environmental changes, not the disposal of waste products.
C. Sensing changes in the environment and then reacting or responding to them: Responsiveness refers to the ability of organisms to detect stimuli, such as changes in temperature, light, or internal conditions, and to respond in ways that maintain survival and homeostasis.
D. The necessity for all organisms to reproduce: Reproduction is an essential functional characteristic of life, but it is distinct from responsiveness. It ensures continuation of the species, while responsiveness deals with immediate reactions to environmental changes.
