B Correct answer
Explanation

The FIND function in SAS searches for a substring and returns the starting position. In 'Italy, Russia, ireland', searching for 'i' finds the first occurrence at position 12 (the 'i' in 'ireland'). FIND is case-sensitive by default, so it skips the 'I' in 'Italy' at position 1. The return value is a position number, not the matched string.
