Solution

The correct option is C Conjugation
Spirogyra can reproduce both sexually and asexually. In vegetative reproduction, fragmentation takes place. Sexual reproduction is of two types:
Scalariform conjugation, which requires association of two different filaments lined side by side either partially or throughout their length.
Lateral conjugation, where the gametes are formed in a single filament.
Thus, the correct answer is option (C).
