What happens to the insect after it is trapped by the pitcher plant?

The correct option is: It is digested by enzymes in the plant.

Pitcher plants are carnivorous plants that use a modified leaf to attract, trap, and digest insects and other small prey. The insects are attracted to the plant and they become trapped due to the slippery walls and downward pointing hairs or spines that prevent them from climbing out.

Once trapped, the insects are slowly digested by enzymes secreted by the plant, which break down the insect's body into nutrients that the plant can absorb. This process can take several days to several weeks, depending on the size of the insect and the species of pitcher plant.
