Which complication to phylogenetic inference is most likely to be widespread in a group of species that have undergone an evolutionary radiation?
a. high rates of similarity because of homoplasy
b. introgression of genes between species
c. great variability of the rates of molecular evolution incomplete lineage sorting
d. none of these are consistently an issue in evolutionary radiations.

C

Explanation:

Complication to Phylogenetic inference is most likely to be widespread in a group of species that have undergone an evolutionary radiation because of  Great variability of the rates of molecular evolution Incomplete lineage sorting.

Incomplete lineage sorting: It is a characteristic Phylogenetic analysis where trees produced from single gene differ from population or species level tree.

option c is correct.
