@ Asif

Dear I agree with you, Correct answer is Record. I was also thinking it was Table but I can confirm Record is the right answer. Thanks for sharing your thoughts as It has clarified the small difference in both.

Yes Record is the right Option..
Table is Logical unit of Work ..and Collection of tuples and fields ..
e.g

Name Age Address -> are the fields
Touqeer 22 Sukkur -> as Whole these three are related fields .. and it is called record ..
and other records makes it as Table

(a) Formating (b) Defregmenting (c) Spooling (d) compressing (e) none of these

asking for Speed up disk Access ... so the Defregmenting is right option ..
