By applying the gas law equation (P1V1/T1 = P2V2/T2), we can solve for the final temperature (T2) by rearranging the equation as T2 = (P2V2/T1)*P1V1. Since the pressure is not given in the problem, we can assume it remains constant. Therefore, T2 = (1.75/2.50)*298 = 209 K. The change in temperature is final temperature - initial temperature, which gives us -89 K (209 K - 298 K = -89 K). Therefore, the correct answer is C.
