The correct answer is: Increase school enrollment.
Shala Praveshotsav is an annual campaign in Gujarat, India, that aims to increase school enrollment. The campaign is held in the month of June, and it is organized by the Gujarat government. The campaign includes a number of activities, such as rallies, street plays, and door-to-door visits. The campaign also provides free textbooks and uniforms to students.
The campaign has been successful in increasing school enrollment in Gujarat. In 2017, the campaign helped to enroll over 1.5 million children in school. The campaign has also been praised for its innovative approach to education.
The other options are incorrect because they are not the main goals of the Shala Praveshotsav. Renovating school buildings, distributing free textbooks, and training teachers are all important activities, but they are not the main focus of the campaign. The main goal of the Shala Praveshotsav is to increase school enrollment.
