Detailed explanation-1: -The kingdom is the taxon that contains the largest number of species. It is the broadest division in which the organisms are grouped in taxonomy. R.H Whittaker gave the five-kingdom classification. This classification includes kingdoms Monera, Protista, Fungi, Plantae, and Animalia.

Detailed explanation-2: -The animal kingdom is the largest kingdom with over 1 million known species. All animals consist of many complex cells. They are also heterotrophs.

Detailed explanation-3: -Taxon is a unit of classification and represents a category or rank in the hierarchy of classification. The largest taxon is the Kingdom.

Detailed explanation-4: -The order ranks below the class and above the family in the taxonomic hierarchy. The groups in an order have more in common with each other than they do with other members of the same class.

Detailed explanation-5: -The number of organisms increases from Species to Kingdom, whereas number of similar characteristics decreases from species to kingdom. Among class, order, phylum, family, the taxonomic category which is placed below the kingdom and is with higher number of organisms is phylum. So, the correct option is ‘Phylum’.
