The format specifier "%15.2f
" specifies that the output should be a floating-point number with two digits after the decimal point, in a field of 15 characters width, left-justified. The "
" represents a newline character that causes each number to be printed on a new line. Therefore, option C is the best choice for the given requirement. Option A does not specify the number of digits after the decimal point and option B does not specify the field width. Option D does not include a newline character.
