We find the required number of page transfer is 10. So, increasing the number of pages need not necessarily reduce the number of page faults. It is the actual sequences of references that decides.

Explanation:
When the number of available page frames is increased to 4, it means that there are more page frames available in the system for storing pages. This can have an impact on the number of page transfers that occur.
Page Frames and Page Transfers:
In a computer system, page frames are used to store pages that are currently being used by processes. When a process requires a page that is not currently in a page frame, a page transfer occurs. This means that the page needs to be fetched from secondary storage (such as a hard disk) and brought into a page frame in main memory.
Impact of Increasing Available Page Frames:
When the number of available page frames is increased to 4, it means that there are more page frames available for storing pages. This can have the following impact:
1. Reduced Page Transfers: With more page frames available, the likelihood of a page being already present in a page frame increases. This reduces the need for page transfers, as the required pages are more likely to be found in the available page frames.
2. Improved Performance: Fewer page transfers mean that the system can avoid the overhead associated with fetching pages from secondary storage. This can lead to improved performance, as the system can access pages more quickly from the main memory.
3. Increased Efficiency: With more page frames available, the system can keep a larger number of frequently accessed pages in the main memory. This can result in better utilization of available memory resources and overall improved system efficiency.
Conclusion:
In conclusion, when the number of available page frames is increased to 4, the number of page transfers decreases. This can lead to improved performance and efficiency in the system. Therefore, the correct answer is option 'B' (Increases).
