Answer 1

The correct option is A J. Muller in 1850

The structure of 'tornaria larva' was first described by J. Muller in 1850. He suspected it to be the larva of starfish. Later, in 1869, Metchinkoff found that it was the larva of Balanoglossus clavigerus. The name tornaria was given to it because of its habitat of rotating in circles.

So, the correct answer is option A.
