### SQL Update Statements to Increase SalaryGiven an Employee table with columns for `salary` and `dept`, to raise the salaries of all employees in the sales department by 10%, we could write one of the following SQL statements:1. **Option A:** ```sql UPDATE salary SET salary = salary*1.10 WHERE dept='sales'; ```2. **Option B:** ```sql UPDATE Employee SET salary = 1.10 WHERE dept='sales'; ```3. **Option C:** ```sql UPDATE Employee LET salary = salary*1.10 WHERE dept='sales'; ```4. **Option D:** ```sql UPDATE Employee SET salary = salary*1.10 WHERE dept='sales'; ```### Analysis- **Option A:** Incorrect. Using `UPDATE salary` is not appropriate since `salary` is a column, not a table. - **Option B:** Incorrect. This statement sets the `salary` column to a constant value of `1.10`, which means it won't increase the salary by 10% correctly.- **Option C:** Incorrect. The use of `LET` is syntactically incorrect in the context of an SQL `UPDATE` statement.- **Option D:** Correct. This statement accurately reflects the intention to update the `salary` column by multiplying it by `1.10` for all employees in the 'sales' department.

This question deals with SQL (Structured Query Language), which is used to manage and query…
