In the context of evolution, sweet potato and potato are examples of:

The correct answer is Option (1) → Analogous organs

Analogous organs do the same job but have a different origin and basic structure. Sweet potato and potato both store food. But the sweet potato is a modified root, while the potato is a modified stem. So they are analogous organs.

(1) Analogous organs — Correct. Same function (food storage), different origin (root and stem).

(2) Homologous organs — Incorrect. Homologous organs share the same origin and basic structure but do different jobs, like the thorn and tendril of Bougainvillea and Cucurbita. A root and a stem do not share an origin.

(3) Convergent evolution — Incorrect. Convergent evolution is the process that produces analogous organs. The question asks what the two organs are, and they are analogous organs.

(4) Divergent evolution — Incorrect. Divergent evolution produces homologous organs, not analogous ones.
