We can use Charles's Law, which states that the volume of a gas is directly proportional to its temperature if pressure is constant. Mathematically, V1/T1 = V2/T2. 
Plugging in the given values, we get (3.62 L)/(21.6°C + 273.15) K = (3.49 L)/(T2). 
Solving for T2, we get T2 = (3.49 L)/(3.62 L) x (21.6°C + 273.15) K = 284 K. Therefore, the answer is choice B.
