At r.t.p, you may be aware that 1.00 mol of any gas occupies 24 dm^3.
You should also know that number of particles = 6.02 x 10^23 x moles
What does this imply about the number of particles of gas in options C and D?

you can calculate by converting first two options into dm3 as well..convert all of them into moles..then you will get to the answer...
