In which Indian state is the famous Pushkar Fair, one of the largest livestock and cultural fairs in the country, held every year?

Introduction / Context:
This question connects Indian geography with culture and festivals by asking about the location of the Pushkar Fair. The Pushkar Fair is one of the largest camel and livestock fairs in the world and has become a major cultural and tourist event. Knowing which state hosts this fair helps reinforce your understanding of how traditional activities are linked with specific regions in India.

Given Data / Assumptions:

• The fair mentioned is the Pushkar Fair.
• We are asked to identify the Indian state where this fair is held.
• Options include Bihar, Uttar Pradesh, Madhya Pradesh and Rajasthan.
• We assume standard information from Indian tourism and culture resources.

Concept / Approach:
Pushkar is a town located near Ajmer in the state of Rajasthan. The Pushkar Fair (also called Pushkar Camel Fair) takes place on the banks of the Pushkar Lake and near the famous Brahma temple. Rajasthan is widely associated with desert landscapes, camels and colourful fairs, which matches the imagery of the Pushkar Fair. The other states listed do not contain the town of Pushkar and are not linked with this particular event.

Step-by-Step Solution:
Step 1: Recall that Pushkar is the name of a town famous for a camel fair and a Brahma temple. Step 2: Remember that Pushkar lies in Rajasthan, not in Bihar, Uttar Pradesh or Madhya Pradesh. Step 3: Connect the Pushkar Fair with the broader image of Rajasthani desert culture. Step 4: Check the options and locate Rajasthan among them. Step 5: Select Rajasthan as the correct answer.

Verification / Alternative Check:
You can verify this by recalling travel shows, tourism posters and exam guidebooks that clearly describe the “Pushkar Camel Fair in Rajasthan.” The fair is often mentioned along with other Rajasthani tourist attractions like Jaipur, Jodhpur and Udaipur. None of the other states on the list is advertised as hosting this event, which confirms that Rajasthan is the correct state.

Why Other Options Are Wrong:
Option a (Bihar) is known for sites such as Bodh Gaya, not the Pushkar Fair. Option b (Uttar Pradesh) has cities like Varanasi and Agra, but no town named Pushkar where such a fair is held. Option c (Madhya Pradesh) is associated with places like Khajuraho and Sanchi, not with the Pushkar Fair. Thus, these options do not match the geographical and cultural facts described in the question.

Common Pitfalls:
Sometimes students answer quickly based only on familiarity with state names and may accidentally pick the wrong option if they do not carefully recall where Pushkar is located. Another pitfall is confusing different fairs such as Kumbh Mela in Uttar Pradesh with Pushkar Fair in Rajasthan. To avoid this, remember the specific association: Pushkar town and camel fair are distinctive features of Rajasthan's cultural landscape.

Final Answer:
The Pushkar Fair is held in the state of Rajasthan.
