Question
Which of the following is a long-short day plant?
Explanation
The right choice is B: Bryophyllum. In PHOTOPERIODISM, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Trifolium; C) Rice; D) Wheat. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
