@test I think correct answers are definitely B and perhaps A. C is not correct because partial DML only helps in handling errors without rolling back the entire transaction, it doesn't directly address transaction control or governor limit avoidance.
B. Use the Database.Savepoint method to enforce database integrity.
C. Use partial DML statements to ensure only valid data is committed.
Reasoning:
Database.Savepoint method: Savepoints allow you to roll back a transaction to a specific point and are useful for enforcing database integrity and ensuring transaction control.
Partial DML statements: Splitting DML operations into smaller, logical chunks allows you to handle errors more gracefully and avoid hitting governor limits by processing smaller amounts of data at a time.
why C is not correct?
A & C ?
