Which meaning of 'specified' best fits formal instructions?

• A. Defined
• B. Thoroughly commented or explained
• C. Stated in detail
• D. Expressly stated

Answer: (D)

Precision and explicitness in language are what formal instructions require. Specified means something is clearly and explicitly laid out, with exact terms written so there’s no ambiguity. Expressly stated captures that direct, unambiguous wording—the instruction is given in a way that leaves little room for interpretation beyond what is written. The other senses differ: defined refers to giving a precise definition, which isn’t the same as the instruction needing to be explicit; stated in detail adds emphasis on length or thoroughness, which isn’t necessary for the requirement; and thoroughly commented or explained implies extra analysis or commentary rather than a straightforward, explicit directive.
