Which of the following is a valid variable name in Python?Points:1I don't knowglobalmy_variable$price2name

1. "I don't know" - This is not a valid variable name because it contains spaces and special characters.
2. "global" - This is not a valid variable name because "global" is a reserved keyword in Python.
3. "my_variable" - This is a valid variable name. In Python, variable names can contain alphanumeric characters (a-z, A-Z, 0-9) and underscores (_). They must start with a letter or an underscore.
4. "$price" - This is not a valid variable name because it starts with a special character ($). In Python, variable names cannot start with a number or a special character.
5. "2name" - This is not a valid variable name because it starts with a number. In Python, variable names cannot start with a number.
