To achieve hard-Weinberg equilibrium, certain conditions must be made.
These conditions are:
1. There is noo mutation, 
2. Existence of random mating,
3. There should be no natural selection
4. There is the infinite population size 
5. No migration
Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium
