'Parliament' is related to 'Great Britain' as its national legislature. In the same way, 'Congress' is related to which country as its national legislature?

Introduction / Context:
This is an institution-to-country mapping. “Parliament” denotes the legislature of Great Britain (UK). We must match “Congress” to the country for which it is the national legislature.

Given Data / Assumptions:

• Parliament → United Kingdom.
• Congress → United States of America.
• Other countries in options: Japan (Diet), India (Parliament), Netherlands (States General).

Concept / Approach:
Identify the canonical name of the legislative branch for each country and pair “Congress” accordingly. In the USA, the bicameral national legislature is called “Congress” (Senate + House of Representatives).

Step-by-Step Solution:

Verification / Alternative check:
Cross-check other options’ legislative names: Japan (National Diet), India (Parliament), Netherlands (States General). None equals “Congress”.

Why Other Options Are Wrong:

• Japan: Legislature is the National Diet.
• India: Uses “Parliament”, not “Congress”.
• Netherlands: Uses “States General”.
• Canada: Parliament, not “Congress”.

Common Pitfalls:
Assuming “Congress” is a generic term used by many countries; in this specific national sense, it identifies the U.S. legislature.

Final Answer:
USA
