How should a CQRS system handle a high-frequency update scenario where the read model lags significantly behind the write model?

A. By forcing the command side to wait until the read model confirms it has processed the event before returning.

B. By switching to a synchronous projection model that shares the same database transaction as the command handler.

C. By increasing the hardware specifications of the projection engine until the lag is reduced to under 10ms.

D. By implementing a 'Version Header' or 'Sequence ID' that allows the UI to detect and wait for relevant updates.
