To answer this question, let's break down the code and analyze each step:
The given code is:
names = ['Amir', 'Barry', 'Chales', 'Dao']
print(names[-1][-1])
The variable names is a list that contains four elements: 'Amir', 'Barry', 'Chales', and 'Dao'.
In the print statement, names[-1] is used to access the last element of the list, which is 'Dao'. Then, [-1] is used again to access the last character of the string 'Dao', which is 'o'.
Therefore, the output of the code is the character 'o'.
Option E) O is the correct answer.
