Pick out the wrong statement pertaining to ‘green house’ for the plants ?
  • (A)  ‘Green house’ (made of glass) allows visible sunlight (i.e., short wavelength solar radiation like ultra-violet rays) to pass through the glass and heat up the soil thereby warming up plants inside it
  • (B)  The emitted longer wavelength radiation (e.g., infrared) is partly reflected and partly absorbed by the glass of the green house
  • (C)  ‘Green house effect’ in earth’s atmosphere is due to increasing CO2 level in atmosphere, where CO2 acts like the glass of ‘green house’ thereby warming up the earth’s surface
  • (D)  ‘Green house’ is colder than the outside atmosphere
