An online social media application service company has more than one million customers supported by its countries' offices across three regions globally. The company has decided to distribute its business information management at a regional level. The centralised database relation schemas are simplified as follows: Customer (ID, custName, Address, payment, branchNo*) Branch (branchNo, branchName, regionNo*) Region (regionNo, regionName) Information is required by region. As well as distributing the data regionally, there is an additional requirement to access the customer data either by personal information (by Personnel which requires customer ID, customers' name, address, and branch) or by payment-related information (by Payroll which requires customer ID and payment). For each relation, match the MOST suitable Fragmentation strategy and Replication strategy. a. Full Replication b. Vertical Fragmentation c. Partial Replication d. Horizontal Fragmentation e. No fragmentation is necessary f. No replication . ✓ Fragmentation strategy for Region. Fragmentation strategy for Branch. ✓ Fragmentation strategy for Customer. ✓ Replication strategy for Region. ✓ Replication strategy for Customer g. Random replication h. Mixed (Horizontal and Vertical) Fragmentation
