It should be letter D.
Whatever the formula of a certain substance, a mole of it will always contain 6.022x10^23 molecules. Thus, 6.02x10^24 molecules of any substance contains 10 moles of it, whether it is CO2, CO, or even DNA.

What @Swapnil sontakke said is right. only 1 gm of O2 has 6.022*10^23 molecules.
Therefore 6.023x10^24 no.of moles will be in 10 gm of O2 molecule.
Since in CO only 1 atom of Oxygen is present the answer is C.
Therefore 6.023x10^24 no.of moles will be in 10 gm of O2 molecule.
Since in CO only 1 atom of Oxygen is present the answer is C.

Its 5g molecule because 1g of CO molecule has 6.022*10^23 molecule of CO. Therefore 6.022*10^24 molecules has 10g of CO molecule. Hence out of 10g 5g is for only C.
