The Correct Option is A

Solution and Explanation

The plant body having holdfast, stipe, and frond is characteristic of Laminaria.

Laminaria is a type of brown algae (a member of the class Phaeophyceae). It has a well-developed structure consisting of:
Holdfast: Anchors the plant to rocks or the sea floor.
Stipe: The stem-like structure that supports the fronds.
Fronds: The leaf-like structures that are responsible for photosynthesis.

Other options:

  • Volvox is a colonial green alga and does not have the same structure of holdfast, stipe, and frond.
  • Gelidium is a red alga that typically has a different morphology.
  • Porphyra is a type of red algae, and its structure also differs from that of Laminaria.

Thus, the correct answer is (A) : Laminaria.
