In the prothallus of a vascular cryptogam, the antherozoids and eggs mature at different times. As a result:

  1. A
    there is no change in success rate of fertilization
  2. B
    there is high degree of sterility
  3. C
    one can conclude that the plant is apomictic
  4. D
    self fertilization is prevented

Solution & Step-by-step Explanation

When male and female reproductive organs mature at different times (dichogamy), it ensures that an egg is not fertilized by sperm from the same prothallus, thereby preventing self-fertilization and promoting cross-fertilization (outbreeding).
