In frog:
1. Fertilisation is external, takes place in water while development involves a larval stage called tadpole that undergoes metamorphosis to form the adult.
2. Fertilisation is internal, takes place inside the female body while development involves a larval stage called tadpole that undergoes metamorphosis to form the adult.
3. Fertilisation is external, takes place in water while development involves a larval stage called instar that undergoes paurometabolous metamorphosis to form the adult.
4. Fertilisation is internal, takes place inside the female body while development involves a larval stage called instar that moults 13 times to form the adult.
