Which statement accurately describes a reproductive strategy found in sharks according to the provided text?

  • A: All sharks are oviparous, laying eggs that develop outside the mother.
  • B: Ovoviviparous sharks retain fertilized eggs in the oviduct, and embryos are nourished by the egg yolk.
  • C: Viviparous sharks develop outside the mother's body, receiving nourishment directly from the environment.
  • D: Internal fertilization does not occur in sharks; sperm is transferred externally.

Explanation

The text states: 'Other species are ovoviviparous; they retain the fertilized eggs in the oviduct. Nourished by the egg yolk, the embryos develop into young that are born after hatching within the uterus.' This perfectly matches option B.
