Solution

The correct option is D $i$ , $i i$ , $i i i$ only
The diplontic life cycle will be commonly visible in the gymnosperms as well as angiosperms. But, an Alga called Fucus also shows such a life cycle.
In this life cycle, the diploid sporophyte is dominant and photosynthetic.
It is the independent phase of the plant. The gametophyte stage is also called haploid gametophyte.
Thus, the correct option is C.
