________ grasses are known as elephant grasses.

Answer: Option C

Savannah grasses are known as elephant grasses. Elephant grass is a tall grass that originally came from Africa in 1913. It grows in dense clumps of up to 10 feet tall. In the savannas of Africa it grows along lake beds and rivers where the soil is rich. Local farmers cut the grass for their animals, carrying it home in huge piles on their backs or on carts.
