Correct Option (A)
Statement I is valid. The passage explicitly states that "even those just over the poverty line are subject to multiple economic insecurities of various kinds". This directly supports the assumption that individuals above the poverty line are also prone to suffer from anxiety regarding economic insecurity.
Incorrect Options:
Statement II is not a valid assumption based on the passage. The passage identifies social inequality as a social problem and economic insecurity as an economic problem. While it discusses government policies aimed at mitigating these insecurities, it does not establish a direct causal relationship or claim that the eradication of poverty will inherently result in peace and social equality in the country. Such an inference extends beyond the scope and direct statements provided in the text.
Options B, C, and D are incorrect because they either incorrectly validate Statement II or invalidate Statement I.
