Solution

The correct option is A Zeatin
Cytokinin was discovered as Kinetin (a modified form of adenine) from the autoclaved sperm DNA. But, kinetin doesn't occur naturally in plants so searches were made to identify naturally occurring substance with cytokinin-like activity. And this led to the discovery of Zeatin from corn kernels and coconut milk.
So, the correct answer to the question is 'Zeatin'.
