The correct answer is option 'D', that is Compliance ledger, such as Asset Management.

Explanation:

Blockchain technology has the potential to revolutionize various industries and sectors by providing secure and transparent data management solutions. However, implementing a blockchain solution requires a significant investment of time, resources, and expertise. Therefore, it is essential to choose the right use case to start a blockchain journey.

Here are the reasons why Compliance ledger, such as Asset Management, is a good place to start a blockchain journey:

1. High regulatory requirements: Compliance-ledger-based use cases, such as asset management, have high regulatory requirements, which make them ideal candidates for blockchain technology. Blockchain's immutable and transparent nature can ensure compliance with regulations and reduce the risk of fraudulent activities.

2. Complex data management: Asset management involves complex data management, such as tracking ownership, verifying authenticity, and ensuring compliance with regulations. Blockchain technology can provide a secure and transparent platform for managing such complex data.

3. Cost savings: Asset management involves multiple intermediaries, such as custodians, brokers, and auditors, which lead to high transaction costs. Blockchain technology can reduce these costs by eliminating intermediaries and providing a direct peer-to-peer platform for asset management.

4. Increased efficiency: Blockchain technology can automate many of the asset management processes, such as settlements, reconciliations, and audits, thereby increasing efficiency and reducing the risk of errors.

In conclusion, Compliance ledger, such as Asset Management, is a good place to start a blockchain journey due to its high regulatory requirements, complex data management, cost savings, and increased efficiency.
