<span>A numeric string is created by a cryptographic
algorithm, which is called a hash that is used to validity of a message or authenticity
of a document. The signature is verified by an algorithm that uses the stated
owner of the signature's public key to accept or reject the authenticity of a
signature. A certification authority's digital signature is used to verify the
authenticity of digital certificates and other documents in a PKI.</span>
The answer is a) It improves upon the two-phased commit by requiring that locks be acquired at the start of a transaction.
Reason: The 3PC is an extension or you can say developed from 2PC that avoids blocking of an operation. It just ensures that first n sites have intended to commit a transaction that means it acquires commits or locks before the start of any transaction to avoid any blocking.
Option b) is wrong as it does not allow coordination, it just let all the other sites do their transaction if any other site is blocked, so no coordination is there between sites that they will wait till their coordinator is corrected.
Option c) is wrong as lock operations are shared between other connections as when their coordinator fails, the new coordinator agrees to the old coordinator that they had shared locks before and they can start their transaction.
Option d) is wrong as option a) is correct.

Answer:
"It is 80 cents"
Explanation:
In order to calculate how much this actually is, we would need to multiply this fraction by the value of a whole dollar which is 1. We can divide the fraction 4/5 and turn it into the decimal 0.80 which would make this much easier. Now we simply multiply...
0.80 * 1 = $0.80
Finally, we can see that 4/5 of a dollar would be 0.80 or 80 cents. Therefore Pradeep would answer "It is 80 cents"
