What should you do?

Background
You have a database named HR1 that includes a table named Employee.
You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running.
You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires. Employee Table
You use the following Transact-SQL statements to create, configure, and populate the Employee table:

Application
You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously:
UspA: This stored procedure updates only the EmployeeStatus column.
UspB: This stored procedure updates only the EmployeePayRate column.
The application uses views to control access to data. Views must meet the following requirements:
Allow user access to all columns in the tables that the view accesses. Restrict updates to only the rows that the view returns.
Exhibit

You are analyzing the performance of the database environment. You discover that locks that are held for a long period of time as the reports are generated.
You need to generate the reports more quickly. The database must not use additional resources.
What should you do?
A. Update all FROM clauses of the DML statements to use the IGNORE_CONSTRAINTS table hint.
B. Modify the report queries to use the UNION statement to combine the results of two or more queries.
C. Apply a nonclustered index to all tables used in the report queries.
D. Update the transaction level of the report query session to READ UNCOMMITTED.
