We can use the combined gas law formula to solve this problem.
(P1V1)/T1 = (P2V2)/T2

Substituting the given values, we get:
(0.869 atm)(3.60 L)/(55°C + 273)K = (1.05 atm)(V2)/(25°C + 273)K

Solving for V2, we get:
V2 = (0.869 atm)(3.60 L)(25°C + 273)K / [(55°C + 273)K)(1.05 atm)]
V2 = 2.71 L

Therefore, the gas will occupy 2.71 L at 1.05 atm and 25°C. Hence, the answer is (C).
