In angiosperms, the zygote is formed inside the ovule. 

  • In most of the plants, with the formation of the zygote, all the parts of the flower except the pistil wither and fall off. 
  • In some plants, such as tomato and brinjal, the sepals are persistent and remain attached to the developing fruit.
  • In ovule, the zygote divides several times to form an embryo.
  • Meanwhile, the wall of the ovule becomes hard and it develops into a seed. 
  • With these developments, the wall of the ovary also starts to swell. 
  • As a result, the ovary develops into the fruit. 
  • A thick wall that covers fruit is called the pericarp. 
  • It is protective in function. 
  • When seeds mature, they are dispersed. 
  • Under favourable conditions, these seeds germinate to produce new plants.

Hence, the correct answer is option a.
