Tanya heats 100 g of a liquid with an electric heater which has a constant power output of 60 W. After 100 s the rise in temperature is 40 K. The specific heat capacity of the liquid in \({\text{J}}\,{\text{k}}{{\text{g}}^{ - 1}}{{\text{K}}^{ - 1}}\) is calculated from which of the following?

A.     \(\frac{{60 \times 100}}{{0.1 \times 40}}\)

B.     \(\frac{{60 \times 0.1}}{{40}}\)

C.     \(\frac{{0.1 \times 40}}{{60}}\)

D.     \(\frac{{60}}{{40}}\)
