Solution

The correct options are
A $6.023 \times 10^{23}$ atoms of carbon
C $6.023 \times 10^{23}$ molecules of $C O_{2}$
1 mole $C O_{2}$ contains $N_{A}$ number of molecules.
1 molecule of $C O_{2}$ contains 1 $C$ atom.
$N_{A}$ molecule of $C O_{2}$ contain $N_{A}$ $C$ atoms.
1 molecule of $C O_{2}$ contain 2 $O$ atoms.
$N_{A}$ molecule of $C O_{2}$ contains = $2 \times N_{A} O$ atom
$N_{A} = Avogadro number = 6.023 \times 10^{23}$
