Which of the following is a C3 plant?

Think it through first, then pick an option.

  1. a Sugarcane
  2. b Maize
  3. c Motha grass
  4. d Rice
Answer and explanation

Correct answer: d Rice

Rice is a C3 plant: it is outside the book's C4 list, and most plants are C3.

Why the other options are wrong

  • a Sugarcane: Sugarcane is a C4 plant, given as an example in the book.
  • b Maize: Maize is named in the book as a C4 example, not a C3 one; rice is the C3 plant here.
  • c Motha grass: Motha grass is a C4 example in the book.
