Assertion $(S)$: Kingdom is the largest taxonomic category.
Reason $(R)$: The major group that includes all other groups is called a Kingdom.
$(a)$ Both $S$ and $R$ are true,and $R$ is the correct explanation of $S$.
$(b)$ Both $S$ and $R$ are true,but $R$ is not the correct explanation of $S$.
$(c)$ $S$ is true and $R$ is false.
$(d)$ $S$ is false and $R$ is true.
$(e)$ Both $S$ and $R$ are false.

The correct sequence of taxonomic categories is:

The correct sequence of the various taxons while naming an organism is:

Which of the following is true for organisms of the same species?

As we go from Kingdom to Species, the number of common characteristics $ \dots $ and the number of species $ \dots $.
