Suppose a transaction Taccesses $($for read or write operations$),$ a certain set of objects $(01....,$ Ok$).$ T acquires exclusive locks on $01.....$ Ok in increasing order of their addresses, performs the required operations and releases the locks. The transaction T is guaranteed $[$choose all those which apply and justify$]$: sel strong entity i$)$ serializability and deadlock$-$freedom ii$)$ neither serializability nor deadlock$-$freedom iii$)$ serializability but not deadlock$-$freedom iv$)$ guarantee deadlock$-$freedom but not serializability
