Which office does belong to the divisions CSD, ETISD, FSD, ITSD?

• A. PLANNING, MANAGEMENT AND INFORMATION SYSTEMS DIVISION (PMISD)
• B. ADMINISTRATIVE DIVISION (AdmD)
• C. FINANCIAL MANAGEMENT DIVISION (FMD)
• D. RESEARCH, INVESTIGATION AND INTERNATIONAL TRADE ANALYSIS SERVICE (RIITAS)

Answer: (D)

The central idea is that divisions focused on collecting data, handling statistics, and examining tariff and international trade dynamics are coordinated by an office whose core role is research, investigation, and international trade analysis. The listed divisions — which align with statistical analysis, investigative work, and international trade considerations — naturally fall under an office whose mandate is to conduct research, carry out investigations, and analyze international trade trends. That makes the Research, Investigation and International Trade Analysis Service the best fit, as its explicitly stated functions directly support and integrate the analytical work these divisions perform. The other offices focus on planning and information systems, administration, or financial management, which do not align with the analytical and international trade analysis focus of the divisions in question.
