Explanation:

In medical prescriptions, "Sig" (from the Latin "signa") means "write (on the label)" or "label as follows". "Po" means "by mouth", "Qid" means "four times a day", and "PC" means "after meals". So the abbreviation referring to "label" is "Sig".

Sig (the option with "Sig" as the text)
