Step 1: Recall the conversion factor between grams of protein and kilocalories (kcal).
1 \text{ gram of protein} = 4 \text{ kcal}
According to the nutritional facts, one gram of protein provides approximately 4 kcal.
Step 2: Since the problem provides 1 gram of protein, we can directly use the conversion factor to find the number of kcal.
\text{kcal} = 1 \text{ gram of protein} \times 4 \frac{\text{kcal}}{1 \text{ gram of protein}}
Final Answer
The correct answer is B. 4 kcal.
