Answer:
Its outfile<<number.
However, before this we need to write

Explanation:
The answer is self explanatory.
Answer: hello your question lacks the required option, below are the missing options
A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.
B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.
C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.
D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.
answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )
Explanation:
What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.
Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.
It is a unit of disk space allocation for files and directories. Hope this helps :)
