Solution

The correct option is C Assertion is correct but Reason is incorrect
There are some substances produced in the plant body itself, which affects the growth of the plant called plant hormones or phytohormones or growth hormones.
They affect gene expression, transcription levels, cellular division, and growth.
They specifically do not only increase the rate of reaction, accelerate growth and other related changes but may also suppress these processes.
So, Assertion is correct but Reason is incorrect.
