Solution

The correct option is B Delete
There are three basic types of updates: insert, delete and modify. Delete operation is carried out to remove a tuple from a relation. A particular data record from a table can be removed by performing such a operation. The delete operation can violate only referential integrity, if tuple being removed is referenced by foreign key from tuples in the database.
