cryptochrome

HY5 protein functions as:

Positive regulator of photomorphogenesis (B) is correct here. This is core cryptochrome: once you know the definition or pathway step, Positive regulator of photomorphogenesis is the clear fit. The wrong ones are A) Negative regulator of photomorphogenesis; C) Photoreceptor; D) Hormone. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

PSS-Sec-E-Sensory biology

Pfr induces degradation of which transcription factors?

The right choice is C: PIFs. In PSS-Sec-E-Sensory biology, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) HY5; B) COP1; D) LAF1. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
