Hey Folk,
answer is option ( C )
Because , equal number of volume contains equal number of moles / molecules

Hydrogen atom or hydrogen molecule?
its a law
in mole.concept
wait, I.will say the name of that law
according to avogadro's law, equal no.of all gases under same condition of temp and pressure contain equal no of moles/molecules
so, if in questions, when volume is same for all molecules, their no.of molecules
are same

Answer : The correct option is C.
Explanation :
According to Avogadro's law, at same temperature and pressure condition, equal volume of all gases have the same number of molecules.
Avogadro's law is defined as the volume of gas is directly proportional to the number of moles of gas.
where,
V = volume of gas
n = number of moles of gas
As per the question, the volume of each gases are equal at STP.
Therefore, the number of molecules in 100 ml of each of gas at STP are the same.
