Convert 25 °C to Kelvin.

Explanation:
To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. This comes from the Kelvin scale starting at absolute zero, where 0 K equals −273.15 °C. For 25 °C: 25 + 273.15 = 298.15 K, which is typically written as 298 K when rounding to the nearest kelvin. The other options correspond to different temperatures: 0 °C is 273 K, a very small temperature like about −248 °C is 25 K, and about 49 °C is around 322 K.
