Plant which produce seeds without fertilization are called as:

Apomictic plants

The correct answer is Option (3) → Apomictic plants

Apomixis is a form of asexual reproduction in plants where seeds are formed without the fusion of gametes (fertilization). It allows the plant to produce seeds that are genetically identical to the parent plant. Although seeds, in general are the products of fertilisation, a few flowering plants such as some species of Asteraceae and grasses, have evolved a special mechanism, to produce seeds without fertilisation, called apomixis. Thus, apomixis is a form of asexual reproduction that mimics sexual reproduction.
