The world's largest car park, capable of accommodating around twenty thousand vehicles, is located at which of the following places?

Introduction / Context:
Records related to largest structures and facilities are popular topics in general knowledge examinations. Car parks attached to major commercial complexes need to accommodate huge numbers of vehicles. The world's largest car park is associated with a famous shopping and entertainment complex in North America, and this question tests awareness of that specific location.

Given Data / Assumptions:

- The record being discussed is for the largest car park by parking capacity, not by height or area alone.

- The car park is linked to a well known commercial complex or mall.

- The option that correctly identifies this location will mention both the complex and the city or country where it is situated.

Concept / Approach:
To answer this question, we recall which shopping or entertainment complex is known in general knowledge references for having a car park that can hold around twenty thousand vehicles. West Edmonton Mall in Edmonton, Canada has repeatedly been cited in quiz books as having one of the largest car parks in the world. The other locations in the options also have large parking facilities, but their capacities are generally lower or they are not the traditional answer used in common reference material.

Step-by-Step Solution:
Step 1: Read the question carefully and note the key phrase world largest car park with space for about twenty thousand vehicles. Step 2: Identify which options are very famous for exceptional size or capacity. Step 3: Recall that West Edmonton Mall in Canada has long been described in quizzes and general knowledge books as having an enormous car park with capacity around twenty thousand vehicles. Step 4: Recognise that Dubai Mall, Mall of America, and Marina Bay Sands also have large parking areas but are not usually cited with this exact record in standard general knowledge sources. Step 5: Choose the option mentioning West Edmonton Mall in Edmonton, Canada as the correct answer.

Verification / Alternative check:
If one checks classic general knowledge compilations and reputable quiz websites, West Edmonton Mall is consistently associated with the world record for a car park that can handle around twenty thousand vehicles. While newer facilities may approach similar sizes, the traditional record question refers to this Canadian location. Cross checking several such sources confirms that West Edmonton Mall is the widely accepted answer for examinations that ask about the largest car park in the world.

Why Other Options Are Wrong:
Dubai Mall in Dubai is one of the largest malls in the world and has a huge parking system, but it is not usually given as the textbook answer for this specific record. Mall of America in the United States is also a massive shopping complex with ample parking but does not match the record described in most general knowledge references. Marina Bay Sands in Singapore is known for its hotel, sky park, and casino rather than for record breaking parking capacity. Thus, these three options are plausible but do not correspond with the traditional record linked to West Edmonton Mall.

Common Pitfalls:
A common mistake is to focus only on the fame of the mall or complex and to assume that the most famous building must hold every record. Another error is to choose Dubai or Singapore simply because they are associated with modern mega projects. Careful candidates remember that older quiz questions often highlight West Edmonton Mall and its massive car park, and they rely on that specific association rather than guesswork.

Final Answer:
The world's largest car park is located at West Edmonton Mall in Edmonton, Canada.
