Option B, is a hypothesis about evolutionary relationships

Explanation:

Phylogenetic trees show the evolutionary relationship between different organism and species. The relationship between species is based upon their physical, biochemical, behavioral and biological traits such as body structure, organ and shape, pattern of feeding, reproduction etc. The tree consists of nest or branches where branching represents deviation of a group of organism from the parent characteristic or trait. Now days, sequences of genes are also used to build phylogenetic trees
