A. nums = (1, 2, 3)
B. nums = {1, 2, 3}
C. nums = [1, 2, 3]

Rationale: Square brackets create lists in Python.
2. What is the type of the expression in Python 3?

B. 012
C. 012
D. 0 1 2

012.
5. Which data structure provides key-value mapping?
A. List
B. Tuple
C. Dictionary
D. Set
Rationale: Dictionaries map keys to values ({key: value}).
6. What does len("hello") return?
A. 4
B. 5
C. 6
