Answer: (D)

Verified step by step guidance

1. Step 1: Understand the factors that influence water needs. Water requirements can vary based on environmental conditions, physiological states, and physical activity levels. For example, living in a hot climate increases water loss through sweat, pregnancy increases fluid needs for fetal development, and exercise increases water loss through sweat and respiration.
2. Step 2: Analyze the first factor (I): Living in a hot climate. In hot climates, the body loses more water through sweating to regulate body temperature. This increases the need for water to prevent dehydration.
3. Step 3: Analyze the second factor (II): Pregnancy status. During pregnancy, the body requires additional water to support the growing fetus, amniotic fluid, and increased blood volume. This makes hydration particularly important for pregnant individuals.
4. Step 4: Analyze the third factor (III): Participating in a cardio exercise class. Physical activity, especially cardio exercises, leads to increased water loss through sweat and respiration. This necessitates higher water intake to replace lost fluids and maintain hydration.
5. Step 5: Conclude that all three factors (I, II, and III) contribute to an increased need for water. Therefore, the correct answer is: I, II, & III.
