Modernization, as an objective of economic planning, refers to adopting new and improved methods in economic activities, especially through the use of advanced technology and updated tools. It aims to make the economy more productive and efficient.
(i) Adoption of innovative technology is a key feature, as modernization pushes for advanced machinery, digital tools, and modern production techniques.
(ii) Bringing positive change in social outlook is another dimension of modernization — such as promoting gender equality, education, scientific thinking, and reducing caste-based or superstitious mindsets.
On the other hand, (iii) Equal distribution of income and wealth and (iv) Abolition of intermediaries relate more to social justice and institutional reforms, not directly to modernization.
Therefore, only statements (i) and (ii) are correct.
