________ deletes a data item from a database

A. Delete(Q)

B. Insert(Q)

C. Drop(Q)

D. None of the mentioned

I had been asked this question by my college professor while I was bunking the class.

My doubt stems from Insert, Delete Operations and Predicate Reads in chapter Concurrency Control of RDBMS

Right option is A. Delete(Q)

Best explanation: Delete(Q) deletes a data item from a database. Insert(Q) inserts a new data item Q into the database and assign Q an initial value.
