B) \[CO\]
C) \[N{{O}_{2}}\]
D) \[P{{O}_{4}}\]
Correct Answer: A
Solution :
Green house effect is the result of \[C{{O}_{2}}\] and \[CF{{C}_{s}}\] produced due to incomplete burning of fuel. In this \[C{{O}_{3}}\] permits the sunlight to pass through it to the earth, but absorbs radiation of longer wavelength which normally radiated back from the surface of earth thus causing rise in temperature. CO reacts with blood haemoglobin and damage heart. \[N{{O}_{2}}\] causes bronchitis and lower resistance to influenza.
