1. To check the integrity of your hard disk and fix various file system errors, the Windows utility which should be implemented is Check disk (Chkdsk). This utility is always used with the command line interface (CLI) with the command "chkdsk."
2. An event or action took place and it caused damage to data, hardware, software and processing capability of the computer. From the statement given, security risks are being described. Any event or action that is capable of causing a problem to a computer system is considered to be a security risk and should be prevented through the use of an appropriate utility software.
3. Virus is a software program that can infect, damage and disrupts the whole computer system.

Answer:
Option A is the correct answer choice for the above question.
Explanation:
The computer system needs intercommunication which is done inside the processor to process the task given by the user. There are two types of model is used for intercommunication--
- Message passing and
- Shared memory
The difference between two is that message passing passes the message on two points at a single unit of time whereas shared memory simultaneous shares the multiple messages. That's why shared memory is faster than message passing.
- Hence option A is the correct choice because it also refers to the above concept. While the other is not correct because--
- Option B states that message passing is faster than shared memory which is wrong.
- Option C states that message passing is used for large data but shared memory is used for large data.
- Option D states that shared memory is unavailable in some processor which is wrong.
