2. Only argument II is strong
3. Either I or II is strong

Answer 1

Correct Answer - Option 1 : Only argument I is strong

• Chimneys are tall and slender structures which are used to discharge waste/flue gases at a higher elevation with sufficient exit velocity such that the gases and suspended solids (ash) are dispersed into the atmosphere over a defined spread such that their concentration, on reaching the grounds is within acceptable limits.
• Long chimneys should be installed in industries as it will take the harmful smoke and gases produced in the factories high up in the air so as to reduce its harmful effects on the ground. 
• Pollution at ground level is the most hazardous in the way of being injurious to human and animal life. 
• It can result in increases in pollution in the upper atmosphere. However, Argument I is very strong and alone hold.
