What is the maximal absorption wavelength of erythrolabe?

Explanation:
Erythrolabe refers to the red cone photoreceptors (L-cones) which are most sensitive to long wavelengths of light. Their peak absorption in humans is in the long-wavelength region, around 560 nm. Among the options, 557 nm is the closest to that peak, making it the best match for the maximal absorption wavelength of erythrolabe. The other values correspond to shorter wavelengths associated with blue and green cone sensitivities, not the red cone.
