Answer

Brief Explanations:

Hashes in blockchain act as unique fingerprints for each block of data. They create a chain - like structure where new blocks can be added in a secure and sequential manner. Option 1 is incorrect as hashes don't prevent new block formation or data addition. Option 3 is wrong as hashes in blockchain have nothing to do with alerting the government. Option 4 is incorrect because hashes are not passwords for data blocks.

Answer:

B. Hashes are like fingerprints that make each block of data unique. Blocks form a chain that can only have new blocks added.
