Assuming that the following snippet has been successfully executed, which of the equations are True? (Select two answers)

A and C are the right answers.
The first equation, len(a) == len(b), is true because the len() function in Python returns the length of a sequence, and in this case the sequences that are passed as arguments to the len() function are the lists a and b. Since both lists have the same length, which is 1, the result of the len() function will be the same for both lists, and the len(a) == len(b) expression will evaluate to True.
The second equation, a[0] == b[0], is also true because the variable a is assigned a reference to the list [1], and the variable b is assigned a reference to the same list. Therefore, the two variables refer to the same list in memory, and when the value of the first element of the list is changed using the a[0] = 0 statement, the value of the first element of the list that is referred to by the b variable will also be changed. Therefore, the values of the first elements of the lists referred to by the a and b variables will be the same, and the a[0] == b[0] expression will evaluate to True....
