  1. A. is correct

    This is the log error after we run this program.

    /* WARNING: Length of character variable has already been set.
    Use the LENGTH statement as the very first statement in the DATA STEP to declare the length
    of a character variable.
    */

    Note:
    If the "length statement" would have been defined before "set statement", then the answer would be C!

    The correct answer is A:

    Pls see program below:

    data work.department;
    jobcode = '12345';
    run;

    data work.accounting;
    set work.department;
    length jobcode $ 12;
    jobcode = '123456789012';
    run;

    proc contents data=work.accounting;
    run;

    Its A because the base dataset has already the length set as 5 if you try to reset after set statement it gives you a warning.

  9. Length of character variable jobcode has already been set.
    Use the LENGTH statement as the very first statement in the DATA STEP to declare the
    length of a character variable.
    Proc contens also showed length as 5: see belwo:
    The CONTENTS Procedure

    Data Set Name WORK.ACCOUNTING Observations 1
    Member Type DATA Variables 1
    Engine V9 Indexes 0
    Observation Length 5
