Answer

Brief Explanations:

An extended definition goes beyond a simple statement and may include etymology, examples, or mnemonic devices. The third option not only defines "aa" as Hawaiian lava that solidifies into sharp, jagged rock but also provides a mnemonic (the "ah! ah!" sound) to help remember it, making it an extended - definition.

Answer:

C. Hawaiian lava flows that solidify into sharp, jagged rock are called "aa." I always remember the name by imagining that trying to walk over these rough surfaces made ancient Hawaiians yell "ah! ah!" in pain.
