The \"Hopman Cup\" is an international mixed team tournament related to which sport?

Introduction / Context:
The Hopman Cup is a well known international mixed team event that appears frequently in sports general knowledge questions. Knowing which sport this cup belongs to is important for aspirants preparing for competitive exams where trophies and tournaments are standard topics.

Given Data / Assumptions:

• The tournament is named the Hopman Cup.
• We must identify the sport with which it is associated.
• The options are cricket, badminton, lawn tennis and football.
• We assume the question refers to the international mixed team tennis tournament played on hard courts.

Concept / Approach:
The Hopman Cup is a unique mixed team event in tennis where male and female players represent their countries and play both singles and mixed doubles. It is not part of the official ATP or WTA tours but has been a significant exhibition style event. Recognising it as a tennis tournament is the key idea.

Step-by-Step Solution:
Step 1: Read the name Hopman Cup and recall in which sports news context it appears. Step 2: Remember that the Hopman Cup is held in Australia and involves mixed teams playing singles and mixed doubles in tennis. Step 3: Compare this memory with the four options given. Step 4: Notice that such a mixed gender team format is standard in tennis and not in cricket or football. Step 5: Choose lawn tennis as the correct answer.

Verification / Alternative check:
Checking official tournament descriptions or sports encyclopedias will confirm that Hopman Cup is a tennis event. Pictures and reports from the event show tennis courts and famous tennis players representing their countries, leaving no ambiguity about the sport.

Why Other Options Are Wrong:
Cricket: There is no major international mixed gender team cricket tournament called Hopman Cup.
Badminton: Although badminton has mixed doubles, Hopman Cup is not a badminton competition; famous badminton cups include Thomas Cup and Uber Cup.
Football: Football tournaments are organised differently and do not feature an event named Hopman Cup in standard GK sources.

Common Pitfalls:
The main pitfall is confusing Hopman Cup with other cups of similar sound or assuming it belongs to badminton because badminton also has mixed events. Another mistake is to guess randomly without recalling that many tennis exhibitions and tournaments use the word Cup in their names. Carefully memorising commonly asked tennis cups and tournaments helps avoid these errors.

Final Answer:
The Hopman Cup is related to the sport of Lawn tennis.
