Assume that variables k and num have both been initialized to 10, which of the following is true?
A) id(k), id(num) and id(10) will each give a different result
B) id(k), id(num) and id(10) will all give the same result
C) id(k) and id(num) will be the same because they are variables, but not id(10) because it is an immutable value
D) It depends on the order k and num were initialized

In Python, small integers (including 10) are cached and reused, so the id (memory address) of an integer object with the same value will be the same. Therefore, `id(k)`, `id(num)`, and `id(10)` will all give the same result because `k`, `num`, and the literal `10` all refer to the same integer object in memory.
