In remote sensing, vegetation gives maximum reflectance in which spectral band?

Answer: Option A

In remote sensing, vegetation gives maximum reflectance in NIR spectral band.
NIR is a near-infrared radiation band of spectrum, the NIR bands become weaker and weaker as the wavelength region goes down to a shorter wavelength region. While in remote sensing, vegetation cover gives maximum reflectance in the NIR band.
Remote sensing measures the wavelengths of light absorbed and reflected by the green plants, and the presence of pigments in leaves strongly absorbs wavelengths of visible Red light.
