Solution
The correct option is A Lichens
In a highly industrialized area, lichens will be virtually absent as these area will be highly polluted and lichens are useful bioindicators for air and water pollution specially for sulphur dioxide pollution. Their efficient absorption systems results in rapid accumulation of sulphur when exposed to high levels of sulphur dioxide pollution and the algal partner are most affected by the sulphur dioxide as chlorophyll is destroyed and photosynthesis is inhibited.So, the correct answer is option B.
