A Correct answer
Explanation

To solve this question, the user needs to know that the LEFT function extracts a specified number of characters from the left side of a given string. The CAST function converts a given expression to a specified data type. The LEN function returns the number of characters in a given string.

In this case, the LEFT function is extracting the first three characters from the string '026-100', which results in '026'. The CAST function is converting this string to an integer data type, resulting in the value 26. The LEN function then determines the number of characters in the resulting string, which is 2. Therefore, the correct answer is:

The Answer is: B. 2
