The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion
Fertilized ovules ripen into seeds. The seeds are covered by fruits. A fruit is technically a ripened ovary. Gymnosperms contain ovules but they lack ovary, therefore, seeds are formed but fruits are not formed. Angiosperms contain both ovule and ovary and therefore, are seed bearing fruit forming plants.
