Step 1: Understanding responsibility. 
  
Responsibility in an organization is shared between subordinates and officers. While officers are responsible for overall decision-making and leadership, subordinates share in the responsibility for executing tasks and following through on their assignments. Responsibility is not solely on one level but shared across both levels. 
Step 2: Analyzing the options. 
  
(A) Subordinate: This is partially correct, as subordinates have responsibility for their tasks. 
  
(B) Officer: This is also partially correct, as officers are responsible for overall management and supervision. 
  
(C) Both (A) and (B): Correct. Responsibility is shared between both subordinates and officers in an organization. 
  
(D) None of these: This is incorrect because the correct answer is (C). 
Step 3: Conclusion. 
  
The correct answer is (C) Both (A) and (B), as responsibility is shared between both subordinates and officers.
