Cytokinin helps in delaying the leaf falling and senescence by
1 Overcoming apical dominance
2 Promoting cell division
3 Promoting cell elongation
4 Promoting nutrient mobilisation
Explanation:
Cytokinins help overcome the apical dominance. They promote nutrient mobilisation which helps in the delay of leaf senescence.

Natural kinetin occurs in
1 Coconut milk
2 Pineapple
3 Corn
4 None of them
Explanation:
Cytokinins have specific effects on cytokinesis, and were discovered as kinetin (a modified form of adenine, a purine) from the autoclaved herring sperm DNA. Kinetin does not occur naturally in plants. Search for natural substances with cytokinin-like activities led to the isolation of zeatin from corn-kernels and coconut milk.
