Molar mass of CO2 = [(12) + 2(16)] g
                             = (12 + 32) g
                             = 44 g.
44 g of CO2 contain ---------> 1 mol molecules of it
1 g of CO2 contain  ----------> 1/44 mol molecules of it
Now, to find no. of moles in 0.44 g of CO2 multiply both the sides by 0.44
0.44 g of CO2 contain --------> 0.44 X 1/44 mol molecules
                                ---------> 0.01 mol
So, your answer is (d) 0.01
