(C) In $Ulothrix$ and $Spirogyra$,the plant body is haploid $(n)$.Sexual reproduction involves the fusion of two gametes to form a diploid $(2n)$ zygote.Since the organism is haploid,the zygote must undergo meiosis (reduction division) to restore the haploid state.This process occurs during the germination of the zygospore $(2n)$,which results in the formation of haploid zoospores or new filaments.
