We can use the formula: q = mCΔT, where q is the heat absorbed, m is the mass of the substance, C is the specific heat capacity, and ΔT is the change in temperature.

Rearranging for ΔT, we get:

ΔT = q/mC

Plugging in the values given in the problem, we get:

ΔT = 900 cal / (75.0 g x 1 cal/g°C x 1.00)

ΔT = 12.0°C

Therefore, the new temperature will be:

30.0°C + 12.0°C = 42.0°C

Therefore, the best choice is (C).
