The correct options are
A Angiosperms
B Gymnosperms
The kingdom Plantae can be classified broadly into two categories- cryptogams and phanerogams. Cryptogams includes thallophyta, bryophyta and pteridophyta. The reproductive organs of these plants are inconspicuous (those with hidden reproductive organs). No seed production takes place in cryptogams. On the other hand, phanerogams includes angiosperms and gymnosperms. These plants have well-differentiated reproductive parts, which ultimately produce seeds.
