In a block chain, it is trivial to detect any block tampering. Why?

Question $27$ options:

If an adversary wants to change the data in the middle block of the chain, such as block k$,$ since the data of block k has been changed, its hashed value stored in block k is not changed. So it is easy to detect this tampering.

If an adversary wants to change the data in the middle block of the chain, such as block k$,$ since the data of block k has been changed, its hash stored in block k$+1$ is not changed. So it is easy to detect this tampering.

If an adversary wants to change the data in the middle block of the chain, such as block k$,$ since the data of block k has been changed, its compressed valued stored in block k$+1$ is not changed. So it is easy to detect this tampering.

If an adversary wants to change the data in the middle block of the chain, such as block k$,$ since the data of block k has been changed, its hash stored in block k$-1$ is not changed. So it is easy to detect this tampering.
