Solution

The correct option is B Tadpole
The fertilized eggs of urochordates undergo holoblastic and unequal cleavage. The egg develops to form the blastula. The blastula shows upper micromeres and lower macromeres. When the invagination of the macromeres occurs, gastrulation takes place and the structure of gastrula is formed. This gastrula develops into a tailed larva. This larvae is called as tadpole larva.The larva is free-swimming and exhibits all chordate characteristics. It has a notochord, a dorsal nerve cord, pharyngeal slits and a post-anal tail.
Thus, the correct answer is option B.
