**Core Concept:**

The question is asking about the recommended daily energy intake for an adult woman with heavy work, which refers to the amount of energy needed by the body to maintain basic bodily functions and perform physical activities. This is typically determined based on factors such as body weight, body composition, physical activity level, and environmental temperature.

**Why the Correct Answer is Right:**

The correct answer is **D**. The recommended daily energy intake (kcal) for an adult woman with heavy work is calculated using the following formula:

Energy intake (kcal) = Body weight (kg) x 25

For example, if a woman weighs 60 kg, her daily energy intake would be:

Energy intake (kcal) = 60 kg x 25 = 1500 kcal

This calculation assumes that she has a normal body composition and performs heavy work. The 25 kcal/kg is an approximation for an average sedentary adult, but for heavy work, the energy requirement is higher to account for increased physical activity levels.

**Why Each Wrong Option is Incorrect:**

A) This option is incorrect because it suggests a lower energy intake for a woman with heavy work, which may not be sufficient to meet her increased energy requirements from physical activities.

B) Although this option is closer to the correct answer, it is still too low as it does not account for the increased energy needs of heavy work.

C) This option is incorrect as it provides an excessively high energy intake, which can lead to weight gain, obesity, and other related health problems.

**Clinical Pearl:**

Understanding the recommended daily energy intake for various individuals based on their age, sex, body weight, and activity level is crucial for maintaining a healthy body weight and preventing various health issues related to malnutrition or obesity. It is essential for healthcare professionals, nutritionists, and individuals to consider these factors when determining an appropriate daily caloric intake for maintaining good health and performance in physically demanding jobs.
