The total energy radiated from a block body source at constant temperature is collected for one minute and is used to heat a quantity of water. The temperature of water is found to increase from `20^(@)C` to `20.5^(@)C`. If the absolute temperature of the blackbody is doubled and the experiment is repeated with the same quantity of water of `20^(@)C`, the temperature of water will be:

A

`21^@C`

B

`22^@C`

C

`24^@C`
