A option 1,3,4

TS(T1)=7
TS(T2)=11

As we Know that Time stamp increase in forward direction.

T1,T2,T3,T4------ (1,2,3,4-----)

As above T1 is older transaction  and T2 is younger transaction,

So if older transaction request to younger transaction then Older one may wait, release the data by Younger.

So remembrance is WAIT happened.

If T2 is younger transaction request to the T1 older transaction then younger transaction may die several times before acquiring needed data.

So remembrance is  DIE happened
