Verified step by step guidance

1. Understand the relationship between kilocalories (kcal) and kilojoules (kJ). The problem provides the conversion factor: 1 kcal = 4.184 kJ.
2. Set up the conversion formula to find kilocalories from kilojoules: \(\text{kcal} = \frac{\text{kJ}}{4.184}\).
3. Substitute the given value of 1001 kJ into the formula: \(\text{kcal} = \frac{1001}{4.184}\).
4. Perform the division to calculate the number of kilocalories corresponding to 1001 kJ.
5. Compare the calculated value to the provided options to select the closest approximate answer.
