• B. If both assertion and reason are false.
• C. If both assertion and reason are true but the reason is not the correct explanation of the assertion.

Answer 1

The correct option is B If both assertion and reason are false.

Assertion: Complexity of classification increases from kingdom to species.

• Organisms are grouped based on homologies (similarities in anatomical, morphological, and physiological features) into taxa and these groups are given taxonomical ranks: kingdom, phylum, class, order, family, genus, and species.
• Complexity of classification decreases from kingdom to species.

Reason: Common characters decrease from kingdom to species.

• The lower taxa has more shared characters, thus as we move down the hierarchy the number of shared characters increases.
