PLEASE HELP!!!

Consider the reaction below:
2H2(g) + O2(g) →→→ 2H₂O(g)
If K is 10^80 which of the following is a good estimate of equilibrium concentrations of H2, O2 and H₂O, respectively?
1.5 M, 0 M and 10 M, respectively
2. 10 M, 5 M and 10 M, respectively
3.0 M, 0 M and 5 M, respectively
4. 10 M, 5 M and 0 M, respectively
