The correct answer is A. Dahod.
Dahod is a district in Gujarat, India. It is located in the eastern part of the state, and is bordered by the states of Madhya Pradesh and Rajasthan to the east, and the districts of Panchmahal, Kheda, and Anand to the west. The district has a population of over 2.5 million people, and its headquarters is the city of Dahod.
The district of Dahod is characterized by its hilly terrain, and is home to a number of forests. However, the district also has a large population of people, and as a result, the forest cover has been declining in recent years. In 2011, the forest cover in Dahod district was 24.4%, which was the lowest of any district in Gujarat.
The other options are incorrect because they are districts in Gujarat that have a higher forest cover than Dahod. Kheda district has a forest cover of 34.2%, Anand district has a forest cover of 36.4%, and Gandhinagar district has a forest cover of 38.1%.
In conclusion, the correct answer to the question “Which of the following districts of Gujarat has the lowest forest cover?” is A. Dahod.
