Rewards Activities Order
Database Connection
Solve
A new popular app tracks the activities performed by its users and grants them rewards based on each individual's total activities performed in a year. This data is maintained in a database table (activitesinfo), with the following columns: userid, totalactivities, reward. This year, due to fundraising activity, the company has decided to further reward its users by enhancing the reward as per the following formula: If reward < = 4000, increase it by 2%, If 4000 < reward <= 8000, increase it by 4%, If reward > 8000, increase it by 6%.
            The tech team has written three different scripts to calculate increment for each slab, each script is to run as a separate transaction. Here are the three scripts:
Script 1:
            For users with reward <= 4000, set reward = reward * 1.02
            
            Script 2:
            For users with reward > 4000 and reward <= 8000, set reward = reward * 1.04
            
            Script 3:
            For users with reward > 8000, set reward = reward * 1.06
Each script is to be executed separately. Which of the following options will update the rewards as expected:
A: Execute Script 1 followed by Script 2 followed by Script 3
            B: Execute Script 2 followed by Script 3; Script 1 running concurrently throughout
            C: Execute Script 3 followed by Script 2; Script 1 running concurrently throughout
            D: Execute Script 3 followed by Script 2 followed by Script 1
            E: Execute Script 2 followed by Script 3 followed by Script 1
