Which abbreviation means 'as desired, freely'?

• A. ASAP
• B. Ad lib
• C. c/o
• D. Caps

Answer: (B)

The idea being tested is an instruction that means you may act without fixed limits, doing something “as desired” or “at one's pleasure.” The abbreviation that fits this is the one that stands for ad libitum, often shortened to ad lib. It literally conveys freedom to improvise or consume as much as you want, depending on the context—like a musician improvising in a performance or a patient allowed to eat ad libitum. That’s why it’s the best choice for “as desired, freely.” The other options convey different meanings: one means speed (as soon as possible), another is used in addresses or patient notes as care of or complaints, and the last is a shorthand for capsules or capitals, none of which match the idea of acting freely or by choice.
