Hint: Creatures, for example, canines which bring forth youthful ones are called viviparous creatures. Creatures, for example, frogs, reptiles, butterflies which lay eggs.
In oviparous fertilization takes place internally but embryo development takes place externally.
Complete answer:
In order to solve this question, we need to know about both types of fertilization i.e., internal and external fertilization.
In animals, outer treatment is a kind of preparation where the sperm-egg combination happens remotely, outside the female body. The undeveloped organism creates and develops in the outer condition. While in interior treatment, the sperm-egg combination happens inside the female body. In any case, the advancement of undeveloped organisms may occur either inside or remotely. In view of this, creatures are ordered into two, to be specific, oviparous and viviparous creatures.
Thierry Lode currently divided the conventional class of oviparous duplicate into ovuliparity and (true) oviparity:
> Ovuliparity, wherein fertilisation is external, is taken to be the ancestral situation as a rule; the eggs that the lady releases into the surroundings include unfertilised oocytes, and the male fertilises them outdoors in her frame. In whichever shape they're laid, the eggs of maximum oviparous species include a sizable amount of yolk to assist the boom and pastime of the embryo after fertilisation, and occasionally for a while after hatching as well.
> (True) oviparity, wherein fertilisation is internal. This is taken to be the derived situation, whether or not the male inserts the sperm into the lady intermittently or whether or not she actively or passively alternatives it up—the lady lays eggs containing zygotes with a sizable amount of yolk to feed the embryo at the same time as it stays with inside the egg, and in lots of species to feed it for a while afterwards. The egg isn't retained withinside the frame for maximum of the length of improvement of the embryo in the egg, that's the principle difference among oviparity and ovoviviparity. Oviparity takes place in all birds, maximum reptiles, a few fishes, and maximum Arthropoda. Among mammals, the monotremes (4 species of echidna, and the platypus) are oviparous.
Therefore, the answer is b, false!
Additional information:
Advantages of ovoviviparous animals is that, after birth, the young ones are competent enough to feed and capable of living without the need for their mother’s protection.
Note: Oviparous animals have internal fertilization of eggs via copulation. These animals show no umbilical cord therefore, the nourishment is obtained from yolk of the egg. When the yolk is depleted, mother provides additional nutrition in the form of unfertilized eggs and uterine secretions as well.
