Answer:

B. Internal and external

Explanation:

The first egg has a calcareous shell, so we can imagine it is a dry and hard shell, and the egg has a large amount of yolk. These are characteristic of an egg generated from the internal fertilization, where the union of gametes occurs within the animal's body. During copulation the male uses his genitals or copulators to release sperm into the female's body, which results in an egg similar to the one described in the above question. Birds have this type of fertilization.

The second egg has a wet appearance, with gelatinous substances on its surface. These are characteristic of eggs resulting from external fertilization, where gametes fuse outside the female's body in the environment. In external fertilization, there must be water for the male gametes to move to the female. In addition, males need to eliminate large numbers of gametes to ensure they reach the eggs. Fish have this kind of fertilization and this kind of egg.
