How did US authorities treat Japanese-Americans on the islands of Hawaii after the attack on Pearl Harbor on December 7, 1941?

A) They deported them to Japan.
B) They sent them into internment camps on the islands.
C) Apart from a few supporters of Tokyo's policies, they were left alone.
D) They had to wear yellow ribbons on their sleeves for easy identification.

Unlike the mass internment that occurred on the mainland United States, the majority of Japanese-Americans in Hawaii were not interned due to their critical role in the islands' economy and the impracticality of detaining such a large portion of the population. However, the U.S. government did intern a small number of individuals who were believed to be supporters of Tokyo's policies.
