Verified by Experts

The correct Answer is:
C
Ectocarpus and Fucus respectively show haplodiplontic and diplontic life cycle.
Concept Enhancer In Ectocarpus sporic meiosis occurs and haploid biflagellate meiozoospores are formed. They germinate to produce gametophytic thalli. The gametophytes liberate gametes, which fuse to form diploid zygote, which gives rise to a diploid plant

In Fucus, there is a single somatic phase. It is diploid and produces haploid gametes. The fuse during fertilisation to give rise to diploid individual.
