Explanation
The correct answer is Option 4 i.e. Spermatophyta.
Seed-producing plants belong to the Kingdom Plantae. Within the Plantae kingdom, they are specifically classified under the clade Spermatophytes, also commonly known as Phanerogams. This broad group includes all plants that reproduce by means of seeds, which are highly efficient reproductive structures containing an embryo, stored food, and a protective coat. The two main subdivisions of spermatophytes are gymnosperms (naked seeds, like conifers) and angiosperms (flowering plants with seeds enclosed within fruits).
