Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.

In the alveoli, where there is high ${\mathrm{pO}}_2$, low ${\mathrm{pCO}}_2$, lesser ${\mathrm{H}}^{+}$concentration, and lower temperature, the factors are all favourable for the formation of oxxhaemoglobin, whereas, in the tissues, where low ${\mathrm{pO}}_2$, high ${\mathrm{pCO}}_2$, high ${\mathrm{H}}^{+}$concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin.
