Answer: a) hybridization of species, specifically parasites
Explanation:
Hybrid speciation is a kind of speciation that is caused by reproductive isolation from the parent species. In this the hybridization occurs between the two different species which leads to the formation of new species.
The hybrid formed because of the hybridization of the species that belong to the same genus called as interspecific hybrids and those formed between different sub-species are called as intra-specific hybrids.
Here, in the given situation, the hybridization of the different species of parasites due to geographical distribution of parasite due to global trade has resulted which is responsible for co-infections.
