C Correct answer
Explanation

Cytokinins are plant hormones that specifically promote cell division (cytokinesis) and are involved in promoting root formation in tissue culture. They work in conjunction with auxins - high cytokinin to auxin ratio promotes shoot formation, while low ratio (more auxin) promotes root formation. However, cytokinins themselves are directly associated with promoting root initiation in tissue culture experiments. Options A, B, and D are not the primary functions of cytokinins.
