Which A-series function is Operations?

• A. A1
• B. A4
• C. A2
• D. A3

Answer: (D)

In this A-series system, each function has a fixed code, and Operations is tied to a specific code in that scheme. The correct choice is the one that names Operations according to that standard mapping, because it directly identifies the function described by Operations rather than pointing to a different function. The other options correspond to the other functions within the A-series, so they don’t describe Operations. If you memorize which code goes with Operations, you can quickly spot the right match on questions like this.
