• my_list.sort()

  my_list.reverse()

• my_list.sort()

• my_list.reverse()

• my_list.remove("grapes")

Look at the following program:

my_list = ["bananas", "oranges", "grapes", "pineapples", "apples"]

# You pick the code that goes here...

# ...

# ...

print(my_list)

Pick the code that results in the following output:

['pineapples', 'oranges', 'grapes', 'apples']

• my_list.remove("bananas")

• my_list.sort()

  my_list.remove("bananas")

• my_list.reverse()

  my_list.remove("bananas")
