Answer

A

Explanation

The lamina of Dionaea (Venus flytrap) has two lobes which are hinged to the midrib. The leaf margin possesses 12 – 20 curved spiny teeth. When an insect alights on the leaf and touches sensitive hairs, the two lobes of the lamina fold rapidly. The marginal teeth get interlocked to prevent the escape of the prey.
