Correct Option (3)
The passage explicitly raises the question, "What should the portfolio composition of the government be?" and subsequently provides diverse examples. These examples delineate areas where government ownership or investment is deemed appropriate (e.g., rural roads, public health, forest cover) versus areas best left to the private sector (e.g., airlines, steel, regulated industries). This contextual usage indicates that "portfolio composition" refers to the strategic mix or allocation of government investment and ownership across different industrial and service sectors within the economy.
Incorrect Options:
- Option 1: Public sector assets quality. While the passage mentions the "less-than satisfactory performance of the public sector enterprises" as a reason for reviewing its role, the concept of "portfolio composition" as discussed is about the selection and mix of assets the government should hold, rather than primarily assessing the quality of existing public sector assets.
- Option 2: Investment in liquid assets. The discussion in the passage pertains to long-term strategic ownership and investment in various sectors, including infrastructure and public goods, which are typically illiquid. It does not focus on the liquidity of government investments.
- Option 4: Buying return on investment-yielding capital assets. Although profitability and return on investment are considerations in economic decisions, the passage's definition of "portfolio composition" is broader. It encompasses strategic roles, market failures, public goods provision, and regulatory considerations, not solely the acquisition of capital assets based on their immediate ROI potential. The core emphasis is on the appropriate scope of government involvement across sectors.
