Can you call H_2 an Atom?
The question is indeed poorly worded. What the question seems to be saying is that there are $12.04\times10^{23}$ molecules of hydrogen gas/dihydrogen ($\ce{H2}$).

I'm also noting that the correct answer ends with "... $\pu{44.8L}$ of $\ce{H2O}$ present", while there was absolutely no mention of $\ce{H2O}$. The question is quite misleading.
