0^\(\text{o}\)C and 1 \(\text{ atm}\)
B
25^\(\text{o}\)C and 1 \(\text{ atm}\)
C
0^\(\text{o}\)C and 760 \(\text{ mmHg}\)

Understand that STP (Standard Temperature and Pressure) is a set of conditions commonly used as a reference in chemistry to describe gases.
Recall the standard temperature at STP is defined as 0 degrees Celsius, which can also be expressed as 273 Kelvin. This is the freezing point of water.
Recall the standard pressure at STP is defined as 1 atmosphere (atm), which is equivalent to 760 millimeters of mercury (mmHg) at sea level.
Compare the given options to these standard values: temperature = 0^\(\text{o}\)C (or 273 K) and pressure = 1 \(\text{ atm}\) (or 760 \(\text{ mmHg}\)).
Identify the option that matches both 0^\(\text{o}\)C and 1 \(\text{ atm}\) as the correct representation of STP.
