Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
Snapshots provide a backup, but they don't automate the schema migration process itself.

Why it's wrong here
This clears the cache, it doesn't manage schema structure.

Version-controlled migration scripts manage schema changes safely.

Why it's wrong here
Replication is for high availability, not schema management.
