ii)
C
iii)
D
iv)
Explanation: 

Detailed explanation-1: -Natural classification system is based on natural affinities among the organisms. It takes into account external features along with internal features such as ultrastructure, anatomy, embryology and phytochemistry. Such a classification for flowering plants was given by George Bentham and Joseph Dalton Hooker.

Detailed explanation-2: –The natural system of classification is a biological classification based upon morphological and anatomical relationships and affinities. Artificial systems of classification were based on morphological characters such as habit, habitat, colour, number and shape of leaves.

Detailed explanation-3: -A natural system of classification is based on a large number of characters. This increases the amount of information available from the groupings. A phylogenetic system of classification reflects possible evolutionary relationships based on ancestry and descent.
