Explanation

To determine which items from the list can cause land pollution if discarded, we need to analyze each item based on whether it is biodegradable or non-biodegradable.

1. **Log**: Logs are made of wood, which is a natural material. It can decompose over time due to the action of microorganisms. Therefore, logs do not cause land pollution.

2. **Plastic Sandals**: Plastic is a synthetic material that does not decompose easily. It can remain in the environment for hundreds of years. Thus, plastic sandals can cause land pollution.

3. **Used Ball Pen**: Most ballpoint pens are made of plastic and contain non-biodegradable components. When discarded, they contribute to land pollution.

4. **Roasted Chicken**: Chicken is an organic substance that can be broken down by microorganisms. Hence, it does not cause land pollution.

5. **Credit Card**: Credit cards are made of plastic, which is non-biodegradable. Discarding credit cards can lead to land pollution.

6. **Bananas**: Bananas are organic waste and can decompose easily. Therefore, they do not cause land pollution.

Based on this analysis, the items that can cause land pollution if discarded are:
- Plastic sandals (ii)
- Used ball pen (iii)
- Credit card (v)

**Final Answer**: The items that can cause land pollution if discarded are (ii) Plastic sandals, (iii) Used ball pen, and (v) Credit card.
