Let’s break it down:

- **Option 1: //**
- ✅ This is a valid arithmetic operator in Python.
- It’s called floor division.
- It divides two numbers and rounds the result down to the nearest whole number.

- **Option 2: ?**
- Not an arithmetic operator in Python.
- Actually, Python will throw a syntax error if you try to use '?' as an operator.

- **Option 3: <**
- This is a comparison (relational) operator, not arithmetic.
- It checks if one value is less than another.

- **Option 4: and**
- This is a logical operator.
- It’s used to combine conditional statements, but it isn’t arithmetic.

So, here’s what matters:
**Option 1 (//) is the right answer.**
