The answer is A) [0, 2, 3, 4].

In Python, lists are mutable objects which means that they can be modified after they are created. In this case, we have two variables a and b that reference the same list object [1, 2, 3, 4]. When we assign b = a, we are not creating a new list object but rather creating a new reference to the same list object that a references. Therefore, any changes made to b will also affect a.

When we modify b[0] by setting it to 0, we are also modifying the first element of the list object that a references. Therefore, when we print a after modifying b, we get [0, 2, 3, 4].
