Step 1: Identify the subject and action. Part R, "The States need to address," provides the subject ("The States") and the action ("need to address"), making it a suitable starting point for the sentence.
Step 2: Determine the object of the action. Part P, "the problem of losses," logically follows as the object that the States need to address.
Step 3: Add context to the object. Part S, "in the power sector," describes the area where the problem of losses exists, so it follows P.
Step 4: Specify the manner of action. Part Q, "in a time bound manner," describes how the States should address the problem, fitting at the end.
Thus, the coherent sentence is: "The States need to address the problem of losses in the power sector in a time bound manner." This matches the order RPSQ, which is option D.
