Which of the following is true?

  • In 2PL protocol if all exclusive lock are acquired by transactions in only increasing order of their addresses then 2PL protocol is deadlock free.
  • In 2PL protocol if all exclusive lock are acquire by transaction in only increasing order of their addresses then 2PL protocol is starvation free.
  • Both (a) and (b)
  • Neither (a) nor (b)

Correct me if I'm wrong but when they are talking about the address it should be the address of resources right? in that case 4th should be the option
