Use Event Emission: Ensure that contracts B, C, and D emit events whenever their functions are called.

Maintain Transaction Logs: Within contract A, maintain a mapping or an array to log transactions made to each contract.

To display transactions for contracts B, C, and D under their respective internal transactions in contract A, you need to ensure that each transaction is made through a method in those contracts that emits events.

Create Wrapper Functions: In contract A, create wrapper functions for each function you want to call in contracts B, C, and D. These functions should log the transaction details.

Front-End Tracking: If you need to display these internal transactions on a front-end interface, query the events emitted by contract A or the transaction logs maintained in the contract.

Use the delegatecall or call: When contract A interacts with contracts B, C, and D, use the delegatecall or call methods to ensure the context is preserved and transactions are recorded.
