Explanation / Answer

O2 dissloves in water maximum at high pressure and low temperature. So option A.

Explanation- This is because when we increase the pressure of gas over liquid that means we are pushing the gas into the liquid . This has been explained by Henry's law which says that amount of given gas at a particular temperature and given volume of liquid is directly proportional to its partial pressure of the gas in equilibrium with the liquid.

And for temperature condition , if we decrease the temperature then gas random motion will be slower and hence then gas which comes in direct contact with the liquid will be dissolved in the liquid.

So option A .
