The correct answer is c. 660 feet!

The largest figure stretches over 660 feet long—that’s more than two football fields! These ancient designs, made over 1,500 years ago, are best seen from the air, adding to their mystery and wonder.

Some of the most famous figures include:
The Hummingbird – Delicate and symmetrical, with a wingspan over 200 feet.
The Monkey – Curled tail and all, it’s about 300 feet long.
The Human-like Figure – Nicknamed “The Astronaut”, it has big eyes and appears to wave from the hillside.
