An example of ____________ is Carnauba wax

The correct option/answer is Hard wax.

Waxes are organic compounds that hydrophobically coat various surfaces in nature to prevent water loss. They are generally classified into different categories based on their physical properties, texture, and melting points. Carnauba wax, also known as brazil wax or palm wax, is obtained from the leaves of the carnauba palm tree (Copernicia prunifera).

It is widely known as the "queen of waxes" and is characterized by its exceptionally high melting point (around 82-86 °C) and its high level of hardness and brittleness when pure. Because of these distinct physical properties, it is classified as a classic example of a hard wax, making it extremely useful in applications requiring a durable, glossy finish such as car polishes, shoe creams, instrument polishes, and cosmetics.
