Step 1: Identify Neha's specific responsibilities from the case.
Neha is a Manager at NutriBite. She is responsible for implementing the organisation's marketing plans and ensuring her department has the necessary personnel to achieve goals as per company policy.
Step 2: Recall the role of Top-Level Management.
Top managers (CEO, Board of Directors) formulate overall organisational goals, broad strategies, and company-wide policies. Neha is implementing plans, not formulating them, so she is not at the top level.
Step 3: Recall the role of Middle-Level Management.
Middle managers (departmental heads, branch managers) act as a link between top and lower management. Their key duties include interpreting and implementing policies framed by top management, managing their department's operations, and ensuring adequate staffing within their department.
Step 4: Recall the role of Operational (Lower) Level Management.
Operational managers directly supervise workers on the shop floor or at the ground level and handle day-to-day routine tasks. Neha is a Manager overseeing a department, not directly supervising daily operational tasks.
Step 5: Match Neha's duties to the correct level.
Implementing marketing plans (from top management) and ensuring her department has the right personnel are classic middle-level responsibilities.
Step 6: Confirm the answer.
Neha is working at the Middle Level of management.
\[ \boxed{ \text{(B) Middle level} } \]
