Answer:
A) They are not able to interbreed.
Explanation:
Species are the group of individuals that share common morphological features and are able to interbreed to produce fertile progeny. Thirteen different species of finches diversified from ancestral stock to get adapted to available food type. Accumulation of variation resulted in reproductive isolation and gave rise to 13 different species of finches that were no longer able to interbreed and produce fertile offspring.
