Answer 1

The correct option is D Cooking oil, ghee, mayonnaise and fats should be poured down the drains.

• Cooking oil, ghee, mayonnaise and fats should not be poured down the drains.
• Grease from cooking oil, ghee and fats poured down kitchen sinks or toilets mix with paper and plastic waste to form a thick mass.
• As more fat, grease and garbage accumulate, it grows in size, blocks plumbing systems and stops the free flow of wastewater to sewage treatment plants.
