Explanation:

STP stands for Standard Temperature and Pressure. The standard temperature at STP is \(0^{\circ}C\). To convert Celsius to Kelvin, we use the formula \(T(K)=T(^{\circ}C)+273.15\). So, \(0^{\circ}C + 273.15K\approx273K\).

• Option B (\(-273^{\circ}C\)) is incorrect. Converting \(-273^{\circ}C\) to Kelvin gives \(0K\) (absolute zero), which is not STP.
• Option C (\(0K\)) is absolute zero, not STP.
• Option D (\(273^{\circ}C\)) is much higher than STP. Converting \(273^{\circ}C\) to Kelvin gives \(273 + 273.15=546.15K\).

Answer:

A. \(273K\)
