D Correct answer
Explanation

Bacterial genes for auxin biosynthesis (such as iaaM and iaaH from Pseudomonas syringae) can be inserted into plants to induce parthenocarpy - the development of fruit without fertilization. Auxin is the primary hormone responsible for fruit set and development. Gibberellins and cytokinins are not the primary hormones for this purpose.
