The question asks about the Japanese company whose name literally means "three diamonds". Let's explore what this means and identify the correct answer from the options provided:
Mitsubishi: The name "Mitsubishi" is derived from two Japanese words: "Mitsu" meaning three, and "Hishi" (often pronounced bishi when combined with other words) meaning water chestnut, which is similar to a rhombus or diamond shape. Therefore, "Mitsubishi" can be translated as "three diamonds".
Sanyo: Sanyo means three oceans, not related to diamonds.
Mutsuhito: This is not a company's name; it's the personal name of Emperor Meiji of Japan.
Suzuki: This is a Japanese family name and automobile company, but the name doesn't translate to anything related to diamonds.
