@Nethe Please write your comment in ENGLISH!
C is the correct answer. age is taken as missing value……..so less 9 for sure….try it with same data….
C is the right answer. since there are two words in the name, age is considered as missing in the first two observations.In the third observation name has a single word and the age is 9. that is the reason all the observations are printed.
B is right one since the third observation should be . 43 . and
43>9
it use ” ” as the delimiter.
I means it uses a space as the delimiter.
