Option 1 states that both statements are individually true and statement II is the correct explanation of statement I.

Statement I is about the reasons for the tribal movements in the 19th century in India - land displacements and the introduction of forest laws. This statement is generally accepted as true, as tribal communities were often displaced from their lands due to British colonization and the enforcement of forest laws restricted their access to natural resources.

Statement II claims that the Indian national movement resolved the problems faced by the tribals. However, this statement is not supported by historical evidence. While the Indian national movement did strive for independence and social justice, it did not specifically address the issues faced by tribal communities. Therefore, statement II is not the correct explanation of statement I.

Option 2 states that both statements are individually true but statement II is not the correct explanation of statement I. This aligns with the explanation given above, making option 2 the correct answer.

Option 3 asserts that statement I is true but statement II is false. This aligns with the explanation given above and is the correct answer.

Option 4 claims that statement I is false but statement II is true. This is not accurate, as statement I is generally accepted as true, based on historical evidence.
