depleted in red light; active form

enriched in red light; inactive form

depleted in red light; inactive form

Answer:

The light that reaches the lower portion or in the understory is depleted in the red light wavelength.

The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.

Thus, the selected option is correct.
