D

Blue-green

Text Solution

Verified by Experts

The correct Answer is:
a
When a compound absorbs a specific wavelength from the visible light of any colour then the perceived colour of light is the colour complementary to it.Since the given compound absorbs light ranging between 490 nm -500 nm ie,blue colour,its perceived (transmitting)complementary colour is red.
