It must be in NP.

It can be reduced to any NP-complete problem in polynomial time.

It can be verified within polynomial time.

It is at least as hard as any other problem in NP-Complete. (correct)

NP-Hard problems can be verified in polynomial time.

NP-Hard problems are always part of NP.

NP problems are reducible to NP-Hard problems in polynomial time.

NP-Hard problems do not have to be in NP. (correct)

NP-Hard problems are always solvable in polynomial time.

NP-Complete problems can be verified in polynomial time, while NP-Hard problems cannot.

NP-Complete problems are more difficult than NP-Hard problems.

All NP-Complete problems can be reduced to any other NP-Complete problem in polynomial time, but not to an NP-Hard problem. (correct)
