The correct answer is option-3, which means that the Kelvin scale is the only scale of temperature that has its zero set at absolute zero temperature.

Let`s dissect each option to understand why some scales have their zero set at absolute zero temperature and others don`t:

Option-1: Fahrenheit scale does not have its zero set at absolute zero temperature. The zero point on the Fahrenheit scale was originally based on the temperature of a mixture of ice and salt, which is not equal to absolute zero.

Option-2: Celsius scale also does not have its zero set at absolute zero temperature. The Celsius scale is based on the melting point of ice and the boiling point of water, so its zero point is not at absolute zero.

Option-3: Kelvin scale is the correct answer because it is the only scale of temperature that has its zero set at absolute zero temperature. Absolute zero is the lowest possible temperature, where molecules have no thermal energy.

Option-4: This option is incorrect because it suggests that the Celsius scale has its zero set at absolute zero temperature, which is not true.

Therefore, the correct answer is option-3, and only the Kelvin scale has its zero set at absolute zero temperature.
