Answer:A
The Merkle root is a hash of ____
A. All block transaction hashes B. All block transactions C. All block addresses D. All of the above
Explanation: The Merkle root is a cumulative hash of all transaction hashes in the block. From the leaf nodes, transactions are combined in twos to form a single hash which is the root, this process continues up the tree and we have a Merkle tree root hash. When a single transaction in a block changes, so does the root.
