Solution
The correct option is A Carpogonium
Red algae are defined as eukaryotic algae which possess chlorophyll a, phycobilins, floridean starch as food reserve, abundant phycocolloids (like agar, carrageenin, and funori) but lack flagellate cells. Sexual reproduction is oogamous. The male sex organ is called spermatangium or antheridium. It produces non-flagellate male gamete known as spermatium. The female sex organ is flask-shaped and is termed carpogonium. Carpogonium possesses an elongated receptive organ named trichogyne. Spermatia are carried by water currents to trichogyne tips for effecting fertilization. The female sex organ remains attached to the plant and forms a new structure called carposporophyte.
So, the correct option is 'Option B'.
