Q2 Single choice

What do you want from Room when you create a DAO method and annotate it with @Update?

Example:

@Dao
public interface MyDao {
@Update
public void updateUsers(User... users);
}

A
Room generates an implementation that inserts all parameters into the database in a single
transaction.
B
Room modifies a set of entities, given as parameters, in the database. It uses a query that matches
against the primary key of each entity.
C
Room removes a set of entities, given as parameters, from the database. It uses the primary keys to
find the entities to delete.
