float 2B-H-K?;
```

1. The special character ‘-‘
2. The special character ‘?’
3. The variable name begins with an integer
4. All of above
5. None of these

A variable name cannot start with an integer, along with that the C compiler interprets the ‘-‘ and ‘?’ as a minus operator and a question mark operator respectively.
