The ‘Gokak agitation’ in Karnataka was primarily a movement for:

Workers' rights in the textile industry
Land reforms
Promotion of Kannada language
Environmental protection

The correct answer is C. Promotion of Kannada language.

The Gokak agitation was a movement in Karnataka, India, in the 1980s to promote the Kannada language. The agitation was led by the Kannada Sahitya Parishat, a literary organization, and it resulted in the passage of the Kannada Language Promotion and Utilization Act in 1986. The act made Kannada the official language of the state of Karnataka and gave it a preferential status in education, administration, and the media.

The agitation was sparked by a number of factors, including the perceived dominance of the English language in Karnataka, the lack of government support for Kannada, and the growing influence of other languages, such as Hindi, in the state. The agitation was also motivated by a sense of Kannada pride and a desire to preserve the language and culture of Karnataka.

The Gokak agitation was a successful movement that had a significant impact on the status of Kannada in Karnataka. The act that was passed as a result of the agitation has helped to promote Kannada and ensure its continued use in the state.

The other options are incorrect because they do not accurately reflect the goals of the Gokak agitation. Option A is incorrect because the agitation was not primarily about workers’ rights in the textile industry. Option B is incorrect because the agitation was not primarily about land reforms. Option D is incorrect because the agitation was not primarily about environmental protection.
