To match the items of List-I with List-II effectively, we need to understand the strategic terms used in marketing management and align them correctly:

1. Invest Strategy: This strategy involves allocating resources for growth, often through robust marketing efforts. Thus, it matches with ii. Well financed marketing efforts.
2. Protect Strategy: This strategy focuses on maintaining the current market position, requiring selective allocation of resources to key segments to protect the core business. Hence, it aligns with iii. Selective resource allocation.
3. Harvest Strategy: This involves maximizing short-term cash flow from products or services that do not require new substantial investments. Therefore, it correlates with iv. Not warranting substantial new resources.
4. Divest Strategy: Aimed at selling off or phasing out products or business units, often involving no further investments. This matches with i. No receiving of new resources.

Based on the above analysis, the correct matching code is: a-ii, b-iii, c-iv, d-i.

This reasoning explains the correct associations between the strategies and their respective descriptions using common marketing management concepts.
