The relationship is inversely proportional; as temperature increases, volume decreases in the same way.

I've answered this before that I don't like any of the choices; however, b is the closest.
"The relationship is directly proportional; as temperature increases, volume increases in the same way." The part I don't like is the "in the same way". I don't know what that means. The way I remember Charles' Law is "At constant pressure the volume of a gas is directly proportional to the absolute temperature."
The relationship between the volume and temperature of a gas, assuming pressure is constant, is described by Charles's Law. According to Charles's Law, the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin). In other words, as the temperature of a gas increases, its volume also increases, and as the temperature decreases, its volume decreases.
To understand the relationship between volume and temperature in more detail, you can perform an experiment or refer to the ideal gas law equation, which incorporates multiple gas properties. The ideal gas law equation is represented as PV = nRT, where P is the pressure, V is the volume, n is the number of gas moles, R is the gas constant, and T is the temperature in Kelvin.
Here, we can assume that the pressure is constant, which means that P remains constant. By rearranging the ideal gas law equation, we get V = (nR/P) * T. In this equation, we can see that the volume V is directly proportional to the temperature T.
So, the correct statement describing the relationship between the volume of a gas and its temperature, assuming pressure is held constant, is that the volume of a gas is directly proportional to its temperature in Kelvin.
