PIFs promote which developmental program in darkness?

Options

Choose one · Correct answer highlighted

Explanation

Go with B — Skotomorphogenesis. Under PSS-Sec-E-Sensory biology, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Photomorphogenesis; C) Vernalization; D) Circadian rhythm. When two options sound similar, choose the one that matches the textbook definition most tightly.
