Which of the following trophies or cups is associated with the game of field hockey?

Introduction / Context:
Indian sports history includes many tournaments named after patrons, leaders or sponsors. Some trophies are linked to specific sports like cricket, football or hockey. Examination questions often test whether you can match a trophy or cup with the correct sport. Here, the focus is on field hockey, a sport with a rich tradition in India and internationally.

Given Data / Assumptions:

• Several trophy names are provided: Derby, Agha Khan Cup, Merdeka, Vizzy Trophy and Ranji Trophy.
• We must identify which one is associated with field hockey.
• We assume standard historical associations used in general knowledge books and exam guides.
• Each other trophy typically belongs to a different sport.

Concept / Approach:
The Agha Khan Cup is traditionally associated with hockey. It has been one of the important hockey tournaments, particularly in the subcontinent context. By contrast, the Derby is linked to horse racing, Merdeka to football, and Vizzy and Ranji trophies to cricket. Understanding these standard associations helps quickly choose the right answer without confusion.

Step-by-Step Solution:
1. Review each trophy and recall the sport commonly linked with it in general knowledge material. 2. Identify that the Agha Khan Cup is mentioned along with hockey tournaments. 3. Recall that the Derby relates to horse racing, not hockey. 4. Remember that the Merdeka tournament is a football competition and Vizzy and Ranji trophies are for cricket. 5. Conclude that Agha Khan Cup is the only option correctly associated with field hockey.

Verification / Alternative check:
You can verify from general knowledge compendiums and sports trivia books that list major trophies by sport. In these tables, Agha Khan Cup appears under hockey, while Ranji Trophy and Vizzy Trophy are listed under cricket, Merdeka under football and Derby under horse racing. Cross reference from at least two different sources confirms this mapping.

Why Other Options Are Wrong:

• Derby: Commonly refers to horse racing events, especially classic races for thoroughbred horses.
• Merdeka: Known as the Merdeka tournament in football, historically hosted by Malaysia.
• Vizzy Trophy: A university level or first class cricket tournament named after Maharajkumar of Vizianagram.
• Ranji Trophy: India's premier domestic first class cricket championship.

Common Pitfalls:
A typical error is to pick Ranji Trophy or Vizzy Trophy because many Indian sports fans are more familiar with cricket trophies. Another mistake is to think of Merdeka as a hockey tournament due to regional proximity. To avoid this, learners should maintain a small mental list of key hockey trophies such as Agha Khan Cup, Dhyan Chand Trophy and others, and distinguish them from cricket and football cups.

Final Answer:
The trophy associated with the game of field hockey in this list is the Agha Khan Cup.
