Solution

The correct option is C Cocos nucifera
Plant tissue culture is the technique to produce plants with desired quality in in-vitro condition. In this method, plant tissue (explant) is inoculated into the specific nutrient medium with hormones like auxin, cytokinin and gibberellins. Natural plant extracts such as coconut milk, various fruit juices, casein hydrolysate and yeast extract have also been used as supplements to the basal media for growing tissues. Coconut is rich in cytokinin in its endosperm. Thus, the correct answer is option B.
