A runway is being constructed in a new airport as per the International Civil Aviation Organization (ICAO) recommendations. The elevation and the airport reference temperature of this airport are $535 \: m$ above the mean sea level and $22.65^{\circ}C$, respectively. Consider the effective gradient of runway as $1 \%$. The length of runway required for a design-aircraft under the standard conditions is $2000 \: m$. Within the framework of applying sequential corrections as per the ICAO recommendations, the length of runway corrected for the temperature is

1. $2223 \: m$
2. $2250 \: m$
3. $2500 \: m$
4. $2750 \: m$
