Good question for SAS Certification.

Answer is B:

data flowers1;
input type $ 1-5 +1 color $;
cards;
daisyyellow
;
(nb:a CARDS statement do not need 'run statement' as by DATALINES)

Output is Daisy Ellow
+1 means an extra position to the left, it is LIST INPUT (non modified list) so it is based on positions, not on delimiters.
Answer is B.

Oops: extra position to the left, must be to the right
