The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I
Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.  
When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.

Answer:
Vaccinations
Explanation:
For example, if a disease has an R0 of 18, a person who has the disease will transmit it to an average of 18 other people. That replication will continue if no one has been vaccinated against the disease or is already immune to it in their community. So if you have (for example) a vaccination then you're less likely to get it, resulting in a lower R0
