Answer 1

Hint: Mammals, although it has acquired a perfect form, the phenomenon of rearing amphibians is well developed, where dramatic changes in structure and behaviour are observed. Parental care is mostly modified by the parents to raise offspring so that the genus can continue with fewer eggs.

Complete answer:
Among vertebrates the pioneer species that invade land were amphibians In this new environment, they have to face many hostile forces and develop methods and means to overcome obstacles. Of course, it's important to keep the race going so they can ultimately win the fight. It appears that parental care for amphibians in the animal kingdom has evolved independently. There are several ways in which amphibians exhibit parental protection.

Parental care in Alytes obstetricans-
-Alytes obstetricans have a special kind of parental protection. This type of frog is common in France and Italy.
-They say that some males gathered a female on the beach. One of the male grabbed the female by the waist. The male in this position massages and lubricates the excretory cavity of the female, and the female throws out the egg.
-The egg is fertilized while the egg is released from the invading male sperm. After fertilization, the egg wraps around the back of the thigh and pulls it into a hole near the pond. When the eggs are ready to hatch, the male carries them to the nearest water where the larvae emerge. Development and metamorphosis take place in water.

Hence, the correct answer is option (C).

Note: Parental care in other amphibians:
In Gyrinophilus, eggs are laid under rocks in rivers. The eggs are then removed from all parts of the body, and the secretions prevent the growth of mold. The eggs are placed under the surface of the leaves hanging over the water.
The shoot nest is constructed by triton at the buds of trees to lay eggs and raise young, as well as build nests for repair. The entire nest is covered with a gelatinous secret.
In Triton and Leptodactylus, eggs lie under the leaf surface near the water. In Triton, you can glue eggs to seaweed. In Shinobi Salamander, males remain with their eggs for fertilization and are actively attracted.
