Options

A. blue and green, orange and red
B. Red and yellow, blue and green
C. blue and red, orange and yellow
D. green and yellow, blue and red

Answer

To answer the question "Carotenes absorb___________ light and transmit_____________ and hence are orange in colour," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of Carotenes**: Carotenes are pigments found in plants that play a role in photosynthesis. They are classified as accessory pigments.

2. **Understand Light Absorption**: Carotenes absorb specific wavelengths of light. In the case of carotenes, they primarily absorb light in the blue and red regions of the light spectrum.

3. **Determine What is Transmitted**: Since carotenes absorb blue and red light, they reflect or transmit the remaining wavelengths, which are in the yellow to orange range.

4. **Conclude the Color**: The absorption of blue and red light and the transmission of yellow and orange light results in carotenes appearing orange in color.

### Final Answer:
Carotenes absorb **blue and red** light and transmit **yellow and orange** light, hence they are orange in color.
