c. tens of thousands
Reason: a typical person in a developed country like England uses on the order of 100–200 GJ of primary energy per year (food, transport, heating, goods, services, etc.). 1 GJ ≈ 239,000 kcal, so 100–200 GJ/yr ≈ 24–48 million kcal/yr, which is about 65,000–130,000 kcal/day — i.e. tens of thousands of kilocalories per day.
