Question

Adoption of         standards is voluntary and that the standards are reviewed every five years.

• A. Codex
• B. FSSAI
• C. WTO
• D. ISO

Hint:

Recall which body the passage links with voluntary adoption of its standards.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
We must find the body whose standards a country or company may adopt by choice, and whose standards are reviewed every five years.

Step 2: Key Idea:
The passage says that adoption of the ISO standards is voluntary. ISO standards are not laws. They are reviewed on a fixed cycle, which is every five years, so that they stay current.

Step 3: Check Option 1: Codex:
Codex standards are used by countries as a base for national standards. They are recommendations, but the passage does not link the voluntary adoption line to them, and the five year review belongs to ISO. So it is not the best answer.

Step 4: Check Option 2: FSSAI:
FSSAI is the Indian regulator and its standards are legally binding in India. They are not voluntary. So it is wrong.

Step 5: Check Option 3: WTO:
WTO administers trade agreements and settles disputes. It does not issue standards that are adopted voluntarily and reviewed every five years. So it is wrong.

Step 6: Check Option 4: ISO:
The passage places the line on voluntary adoption right after the description of ISO. ISO standards are reviewed every five years. So it is correct.

Final Answer:
The standards that are voluntary and reviewed every five years are ISO standards, option 4. \[ \boxed{4} \]
