Take a look at the following fragments of code:

A.

my_deque = deque()

my_deque.appendleft('a')
my_deque.appendleft('b')
my_deque.appendleft('c')

my_deque.popleft()
my_deque.popleft()
my_deque.popleft()

B.

my_deque = deque()

my_deque.append('a')
my_deque.append('b')
my_deque.append('c')

my_deque.pop()
my_deque.pop()
my_deque.pop()

C.

my_deque = deque()

my_deque.append('a')
my_deque.append('b')
my_deque.append('c')

my_deque.popleft()
my_deque.popleft()
my_deque.popleft()

D.

my_deque = deque()

my_deque.appendleft('a')
my_deque.appendleft('b')
my_deque.appendleft('c')

my_deque.pop()
my_deque.pop()
my_deque.pop()
