Final answer:
The statement is true; sea scallops are one of the largest varieties among scallops, and they can grow up to two inches in height.
Step-by-step explanation:
The statement that the largest varieties of scallops are called sea scallops is true. Among the different types of scallops, sea scallops (Placopecten magellanicus) are indeed one of the largest varieties. They are significantly larger than bay scallops (Argopecten irradians), which are smaller and have a more limited range. Sea scallops can grow up to two inches in height, and they are commonly found in deep, cold ocean waters on the eastern coast of the U.S and Canada.
