Answer

Correct option: A.
More heat to be retained by the enviroment.
$\mathrm{CO}_2$​ is a green house gas, thus it's increase will trap more heat and will cause global warming .
Also increased $\mathrm{CO}_2$​​​​​​​​ will increase the rate of photosynthesis however, $\mathrm{CO}_2$​​​​​​​​ increase doesn't contribute towards deserted conditions. Instead $I,$ lack of water and increased temperature causes deserted conditions and will promote the growth of desert plants.
