To determine which group contains only non-biodegradable items, we need to analyze each group of materials and identify the non-biodegradable items present in each group.
Group A:
- Polythene: Non-biodegradable
- Detergent: Non-biodegradable
- PVC: Non-biodegradable
Group B:
- Plastic: Non-biodegradable
- Bakelite: Non-biodegradable
- Leaf: Biodegradable
Group C:
- Plastic: Non-biodegradable
- Detergent: Non-biodegradable
- Grass: Biodegradable
Group D:
- Wood: Biodegradable
- Paper: Biodegradable
- Leather: Biodegradable
From the analysis, we can see that only Group A (Polythene, detergent, PVC) contains only non-biodegradable items. The other groups have at least one biodegradable item present.
Therefore, the correct answer is Group A.

Non-biodegradable materials are those that cannot be broken down or decomposed by natural processes such as bacteria or fungi. They persist in the environment for a long period of time, causing pollution and environmental damage. The group of materials that contains only non-biodegradable items is:
a) Polythene, detergent, PVC
Explanation:
Polythene:
- Polythene, also known as polyethylene, is a type of plastic that is commonly used for packaging materials, bags, and bottles.
- It is made from petroleum, a non-renewable resource, and it takes hundreds of years to decompose.
- Polythene is not biodegradable and can accumulate in the environment, causing pollution and harm to wildlife.
Detergent:
- Detergents are chemical substances used for cleaning purposes, such as washing clothes, dishes, or surfaces.
- Most detergents are made from synthetic compounds that are not easily biodegradable.
- They can persist in the environment and contaminate water sources, causing harm to aquatic life.
PVC (Polyvinyl Chloride):
- PVC is a type of plastic that is commonly used in construction materials, pipes, and packaging.
- It is a non-biodegradable material that can release toxic chemicals when burned or degraded.
- PVC is known to persist in the environment for a long time, contributing to pollution and environmental degradation.
In conclusion, the group of materials that contains only non-biodegradable items is a) Polythene, detergent, PVC. These materials are harmful to the environment and require proper disposal methods to minimize their negative impact.
