Step 1: Understanding the Concept:
This question tests knowledge of the hierarchical rank structure within the Indian police force, specifically in the state police services.
Step 2: Detailed Explanation:
Let's arrange the given ranks in ascending order (lowest to highest):
B. Constable (PC): This is the lowest rank in the Indian Police, forming the backbone of the force.
C. Assistant Sub-Inspector (ASI): This rank is above a Head Constable and below a Sub-Inspector. It is the first investigative rank in some states.
A. Deputy Superintendent of Police (DSP/DySP): This is a state police service officer rank. It is a gazetted rank, significantly higher than an ASI. A DSP is typically in charge of a police sub-division.
D. Additional Superintendent of Police (Addl. SP): This rank is senior to a DSP and junior to the Superintendent of Police (SP). An Addl. SP often assists the SP in managing a district.
Step 3: Final Answer:
The correct order from lowest to highest rank is:
Constable (B) $\rightarrow$ Assistant Sub-Inspector (C) $\rightarrow$ Deputy Superintendent of Police (A) $\rightarrow$ Additional Superintendent of Police (D).
This corresponds to the sequence B, C, A, D.
