A Cup board always has

Options

A. Clothes
B. Door
C. Shelf
D. Bolt

Answer

To solve the question, "A cupboard always has," we need to analyze the options provided and determine which one is essential for a cupboard. The options given are:

1. Closed
2. Door
3. Shelf
4. Bolt

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Closed**: A cupboard can be closed or open, but it does not always have to be closed. Therefore, this option is not essential.
- **Door**: While many cupboards have doors, some types of cupboards (like open shelves) do not have doors. Thus, this is also not a necessary feature.
- **Shelf**: Shelves are typically found in cupboards and are essential for organizing items like clothes and books. Without shelves, a cupboard would not serve its primary purpose.
- **Bolt**: A bolt is used for locking, but not all cupboards have bolts. A cupboard can still function without a bolt.

2. **Identifying the Essential Feature**:
- From the analysis, we see that while a cupboard may have doors, be closed, or have a bolt, the presence of shelves is crucial for its function. A cupboard without shelves cannot effectively store or organize items.

3. **Conclusion**:
- The best alternative that reflects what a cupboard always has is **shelf**.

### Final Answer:
The best alternative is **Option 3: Shelf**.
