Answer:
The correct option is B,200 new consultants must be hired each year
Explanation:
Applying inventory formula that established relationship with flow rate and flow time,the number of new recruits each year can be determined.

Inventory is quantity of flow units been managed by an organization at a particular point in time,in the case it is 400 employees.
In addition,flow rate is the quantity of flow units making its way around the business at a particular time,that is unknown and expected to be determined.

As a result,400=R*2years
R=400/2 years
R=200 employees
