Non-exercise activity thermogenesis (NEAT) refers to the energy expended for all physical activities other than sleeping, eating, and intentional exercise. It includes posture maintenance, spontaneous movements (fidgeting), household chores, walking for transport, and other routine activities that generate heat and expend calories without formal exercise.

Relevant knowledge points:
- Total daily energy expenditure (TDEE) is composed of basal metabolic rate (BMR), thermic effect of food (TEF), exercise activity thermogenesis (EAT), and NEAT.
- TEF is the energy used to digest and absorb nutrients.
- EAT is the energy expended during and immediately after structured exercise (including excess post-exercise oxygen consumption or EPOC).
- NEAT encompasses non-exercise heat production and activity-related energy use, including some forms of thermoregulation (e.g., shivering or subtle posture-related heat generation).

Step-by-step reasoning:
1. Identify each option’s category:
   - "Maintenance of body temperature": relates to thermoregulation and low-level physical activity (shivering, posture adjustments) that are not intentional exercise — fits NEAT/adaptive non-exercise thermogenesis.
   - "Heat production following exercise": this describes EPOC, the elevated metabolism after exercise, which is part of exercise-associated thermogenesis, not NEAT.
   - "Absorption of nutrients": this is the thermic effect of food (TEF), a distinct component of TDEE.
   - "None of the above": only true if none matched NEAT, but one does.
2. Compare definitions: NEAT is explicitly non-exercise heat and activity-related energy expenditure; maintaining body temperature via non-volitional activity matches this.

Why the correct answer is correct:
Maintenance of body temperature (when achieved through non-exercise activities such as shivering and involuntary muscle activity or constant posture control) is an example of NEAT because it consumes energy outside of deliberate exercise and digestion.

Why other options are incorrect:
- Heat production following exercise = EAT/EPOC (exercise-related), not NEAT.
- Absorption of nutrients = TEF, not NEAT.
- None of the above is false because one option fits.

Conclusion: The correct answer is Maintenance of body temperature, which matches the provided answer.
