A Correct answer
Explanation

Charles's law states that for an ideal gas at constant pressure, volume is directly proportional to absolute temperature: V ∝ T, or V₁/T₁ = V₂/T₂. Cross-multiplying gives V₁T₂ = V₂T₁, which is option A. This means that as temperature increases, volume increases proportionally, and vice versa, when pressure is held constant.
