Solution
The correct option is B Diplontic
In a diplontic life cycle, the dominant free-living phase is the sporophyte, diploid (2n). The sporophyte is photosynthetic. The gametophytic phase is represented by single to few-celled haploid gametophytes. All seed-bearing plants, i.e., gymnosperms and angiosperms, exhibit this type of life cycle. So, the correct option is b.
