Answer:

Which of the following can be used as valid variable identifiers in python.

(ii) total

(iv) data

Rules for variable name:

1. a variable name must start with an alphabet (A-Z, a-z) or an underscore(_)
2. a variable name cannot start with a number
3. a variable name can only contain alpha-numeric characters (A-Z, a-z, 0-9) and underscore (_)
4. variable names are case sensitive

Examples:

name = "Priya"

num1 = 23

city_name = "Lucknow"
