The correct Answer is:
B
In Spirogyra affiniis, the sexual reproduction occurs through conjugation (indirect lateral) in which adjacent cells of same filament conjugate, the protoplast of one cell (male gamete) migrates to the other (female gamete), then these protoplasts fuse to form zygospore which on germination forms, a single new filament. Thus, from two adjacent filaments with 10 cells participating in reproduction will form 10 new filaments.
