We can use the formula:

Q = m * c * ΔT

where Q is the heat required, m is the mass of water, c is the specific heat of water, and ΔT is the change in temperature.

Plugging in the values, we get:

Q = 2500 g * 4.184 J/(g·°C) * (72°C - 27°C)

Q = 470,080 J = 470 kJ

Therefore, the correct answer is (D) 470 kJ.
