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.

Explanation:
Clients that run numerous virtual machines.
<h3>What is a virtual machine?</h3>
- A virtual machine is the virtualization or emulation of a computer system in computing.
- The functionality of a physical computer is provided by virtual machines, which are built on computer architectures.
- Their use may necessitate specialized hardware, software, or a combination of both.
- Virtual machines' primary function is the simultaneous operation of several operating systems on a single piece of hardware.
- Without virtualization, running two different physical units would be necessary to run different operating systems, such as Windows and Linux.
- Through the use of virtualization technologies, virtual machines are made possible.
- Multiple virtual machines (VMs) can run on a single machine thanks to virtualization, which simulates virtual hardware using software.
- The real machine is referred to as the host, and any virtual machines running on it as the guests.
