None of the provided options (a, b, c) are correct. The correct answer is 33.

The question is asking for the sum of 4 and 13/5. To solve this, we first need to convert the whole number 4 into a fraction with the same denominator as 13/5, which is 5. So, 4 becomes 20/5. Now, add 20/5 and 13/5 together, which equals 33/5. Therefore, the correct answer is 33/5.
