Explanation:

Both statements are incorrect.

• Dravidian languages, a family of some 70 languages spoken primarily in South Asia. They are spoken by more than 215 million people in India, Pakistan, and Sri Lanka.
• The Dravidian languages with the most speakers are (in descending order of number of speakers) Telugu, Tamil, Kannada and Malayalam, all of which have long literary traditions.
• Smaller literary languages are Tulu and Kodava.
• There are also a number of Dravidian-speaking Scheduled Tribes, such as the Kurukh in Eastern India and Gondi in Central India.
• Kurukh , also spelt Oraon, are a Dravidian ethnic group inhabiting the Indian states of Jharkhand, West Bengal, Odisha and Chhattisgarh.
• Dravidian place names along the Arabian Sea coasts and Dravidian grammatical influence such as clusivity in the Indo-Aryan languages, namely, Marathi, Gujarati, Marwari, and Sindhi, suggest that Dravidian languages were once spoken more widely across the Indian subcontinent.

Hence option 4th is correct.
