• B. Two species of the same genus
• C. Analogous
• D. Recent introductions

Answer 1

The correct option is C Analogous

Homologous organs :

• Organs with the same structure but different functions are called homologous organs.
• For example, the forelimbs of whale are used for swimming , bats use them for flying, cheetah for running and man for various other purposes.
• Homologous organs have the same basic plan which suggests a common ancestor.

Analogous organs :

• Analogous organs are structurally different but perform similar functions.
• Potato is a stem modification whereas sweet potato is modified root,but both are performing the same function of storage of food. Thus they are an example of analogous organs.

Two species of the same genus :
Two species of the same genus share some common characters.

Final answer :
(B) Analogous
