Answer 1

The correct option is (a) five characters as a decimal integer, then reads the remaining as a string and then scans the first non-whitespace character

To explain I would say: The above format string reads the first five characters as a decimal integer, then reads the remaining as a string until a space, newline or tab is found, then reads the first non-whitespace character.
