Answer: both greenfield assets and brownfield assets.

## Explanation **Greenfield assets** refer to new investments or projects that are built from scratch, typically involving higher risk due to: - Construction risk - Regulatory approval uncertainty - Market entry risk - Higher initial capital requirements - Unproven operational track record **Brownfield assets** refer to existing investments or projects that are already operational, typically involving lower risk due to: - Established operations - Proven track record - Existing cash flows - Known regulatory environment - Lower construction/development risk **Portfolio diversification effect**: A portfolio containing both greenfield and brownfield assets benefits from diversification: 1. **Risk reduction through diversification** - Different risk profiles can offset each other 2. **Different return characteristics** - Greenfield assets typically offer higher potential returns but with higher risk, while brownfield assets offer more stable returns with lower risk 3. **Reduced correlation** - The two types of assets may have different risk factors and market sensitivities **Why option C is correct**: - Combining both asset types creates a more balanced portfolio - The diversification benefit reduces overall portfolio risk compared to holding only one type of asset - While brownfield assets alone (option B) have lower individual risk, the portfolio with both types has even lower overall risk due to diversification benefits **Key concept**: In portfolio theory, diversification across assets with different risk characteristics can reduce overall portfolio risk without necessarily reducing expected returns.
