Best answer
The correct option is (b) Lateral

The explanation: Select name, salary, avg salary from instructor I1, lateral (select avg(salary) as avg salary from instructor I2 where I2.dept name= I1.dept name);

Without the lateral clause, the subquery cannot access the correlation variable I1 from the outer query.
