3rd and 4th awnsers are correct
There are five basic Hardy-Weinberg assumptions:
1. Random Mating -
2. No natural selection - all members of the parental generation survived and contributed equal numbers of gametes to the gene pool, no matter the genotype
3. No genetic drift (random allele frequency changes) - the population is infinitely large.
4. No gene flow - no new alleles were added by immigration or lost through emigration (no migration)
5. No mutation - There must be mutation equilibrium.

The balance of nature is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system
