Answer: B,D

Explanation:

Topics: list referencing list slicing del

Try it yourself:

nums = [1, 2, 3]

vals = nums

del vals[1:2]

print(nums) # [1, 3]

print(vals) # [1, 3]

A list is a mutable data type.

Assigning a mutable data type creates a reference to the same object.

vals and nums will point to the same object in the memory

and when you change one you automatically change the other, too.
