Answer

To solve the question "A clock always has," we need to analyze the given options and determine which one is essential for the functionality of a clock.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks what a clock always has. This implies we need to identify a component that is essential and cannot be omitted from a clock.

2. **Evaluate the Options**:
- **Option 1: Battery** - While many clocks do have batteries, not all clocks require them (e.g., mechanical clocks).
- **Option 2: Numbers** - Clocks often have numbers to indicate the time, but they can also function without them (e.g., digital clocks).
- **Option 3: Alarm** - An alarm is a feature found in some clocks, but not all clocks have this function.
- **Option 4: Needles** - Needles (or hands) are crucial for indicating the time on an analog clock.

3. **Determine the Best Alternative**:
- Among all the options, the needles are essential for a traditional clock to display time. Without needles, you cannot read the time on an analog clock.
- Therefore, the best alternative is **Option 4: Needles**.

4. **Conclusion**: A clock always has needles, as they are integral to its function of displaying time.

### Final Answer:
A clock always has **needles** (Option 4).
