Explanation:

Photoperiodism is the response of plants to the relative lengths of light and dark periods. It stimulates flowering (photoperiodic control of flowering), can trigger spring growth as day lengths change, and also initiates the hardening - off process for dormancy as day lengths shorten in fall. So all the options a, b, and c are correct, meaning the answer is d.
