Let's go through the problem step by step to find the sum of the given numbers: \(11\), \(1\), \(0.01\), \(0.11\), and \(0.111\).
1. Start with the first number:
\(11\)
2. Add the second number:
\(11 + 1 = 12\)
3. Add the third number:
\(12 + 0.01 = 12.01\)
4. Add the fourth number:
\(12.01 + 0.11 = 12.12\)
5. Finally, add the fifth number:
\(12.12 + 0.111 = 12.231\)
Therefore, the sum of \(11\), \(1\), \(0.01\), \(0.11\), and \(0.111\) is:

Hence, the best answer for the question is:
B. 12.231
