Solution

The correct option is B Phytohormone coding genes
Wild Ti plasmid is a large plasmid which contains 200 to 800 kilobase. This plasmid contains genes coding for phytohormones such as auxins, cytokinins and opines. Increased production of phytohormones induce uncontrolled growth of cells leading to tumour formation.
