Read the text and answer questions 30 to 33

Jellyfish are not actually fish. They are invertebrate animals, which means that, unlike fish or people, they have no backbone. In fact, they have no bones at all.

A jellyfish has a stomach and a mouth, but no head. It has a nervous system for sensing the world around it, but no brain. Its body is made almost entirely of water, and that is why you can look through it.

Some jellyfish can glow in darkness by making their own light. The light comes from a chemical reaction inside the jellyfish's body. Scientists believe jellyfish glow for several reasons; for example, the light may scare away predators or attract the small animals that jellyfish like to eat.

Most jellyfish live in salt water, apart from a few types that live in fresh water. Jellyfish are found in oceans and seas all over the world. They live in warm, tropical seas and in the icy waters near the North and South Poles.

Which one creates jellyfish's light?

A
White blood.
B
Nervous system.
C
Chemical reaction.
✓
D
Salt water.
