Question

roland carries out various responsibilities as a part of the u develops departmental policies and promotes other officers
a. deputy commissioner
b. police chief
c. inspector
d. sergeant

Explanation:

To determine the correct answer, we analyze the responsibilities described (developing departmental policies, promoting officers). A deputy commissioner typically has such administrative and policy - making roles along with personnel - related duties like promotions. A police chief is more focused on overall leadership and strategic direction but the description here aligns more with a deputy commissioner. An inspector and a sergeant have more operational or supervisory roles at a lower level and are less likely to be involved in departmental policy development and officer promotions at the scale described.

Answer:

A. deputy commissioner
