Concept:Reproduction can be sexual (involving two parents) or asexual (involving one parent). Plants can reproduce both ways.
Explanation:External fertilization does not happen in asexual reproduction because asexual reproduction does not involve gamete fusion. So statement A is false.
Plants can reproduce both sexually (through flowers and seeds) and asexually (through vegetative propagation, budding, or fragmentation). Statement B is true.
Viviparous organisms give birth to live young after internal fertilization; they do not produce unfertilized eggs. So statement C is false.
Not all viviparous organisms have external fertilization; most have internal fertilization. Hence statement D is false.
Answer:B. Plants have the ability to reproduce both sexually and asexually
