**Core Concept**
The energy requirement for an individual is determined by their basal metabolic rate (BMR), which is influenced by factors such as age, sex, weight, and activity level. For a sedentary person, the energy requirement is generally calculated based on their BMR multiplied by an activity factor.

**Why the Correct Answer is Right**
For a sedentary 60 kg male, the estimated daily energy requirement can be calculated using the Harris-Benedict equation or other formulas that estimate BMR, then applying an activity factor for sedentary work, which is typically around 1.2. This calculation yields an approximate daily energy requirement of 1,900 to 2,000 kcal for such an individual, considering the average BMR for an adult male is about 66 kcal/kg/day for the first 10 kg of body weight, 31 kcal/kg/day for the next 10 kg, and 25 kcal/kg/day thereafter.

**Why Each Wrong Option is Incorrect**
**Option A:** This option would significantly underestimate the energy needs for even a sedentary individual.
**Option B:** While closer, it still underestimates the typical requirement for a sedentary male of this weight.
**Option D:** This option overestimates the energy requirement for a sedentary individual, as it might be more appropriate for someone with a higher activity level.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that energy requirements can vary significantly based on individual factors, including age, sex, and physical activity level, and using standardized formulas can help in estimating these needs.

**Correct Answer:** C. 1900 kcal/d
