• B. Mikimoto
• C. Von Mohl
• D. Haeckel

Answer 1

Answer: (B)

Mikimoto

This secretion surrounds the foreign particle which later becomes hard and glossy. This hard and glossy substance is known as pearl. Pearl is formed outside the mantle but inside the shell of mollusk. The artificial technique of culturing pearls oyster and stimulating pearl formation using artificial devises was first introduced in Japan by Mikimoto.
