Which of the following was NOT one of Hawaii's historical industries?

Coconut oil production is not recognized as one of Hawaii's historical industries when compared to the others listed. Hawaii's historical economic landscape was significantly shaped by industries like whaling, sandalwood, and sugarcane.

Whaling was particularly prominent in the 19th century, as ships would stop in Hawaiian ports for supplies, and whalers would hunt in the rich fishing grounds around the islands. Sandalwood harvesting also played a crucial role in Hawaii's economy, especially during the early 19th century, as sandalwood was highly sought after in international markets for its fragrant wood used in perfumes and incense. Similarly, sugarcane became a major agricultural product that transformed Hawaii’s economy in the late 19th century, leading to substantial immigration and changes in demographic and economic structures.

While coconut oil production has gained popularity and economic significance in modern times, it's not historically recognized as a foundational industry in Hawaii's economic development compared to the others, which were more integral at earlier stages of Hawaii's economic history.
