The correct option is
B 'Prompt Decision-Making: Tool for success'
The given passage repeatedly stresses the importance of timely decision making. It also highlights the downsides of not making or postponing decisions. Hence, the most suitable title for the given passage among the given options is, 'Prompt Decision-Making: Tool for Success'. Option C is correct.
Option A: This passage quotes an incident about a timely decision made by a doctor, which saved his patient. However, the entire passage is not about this incident. It does not dwell on the relationship between the doctor and his patient. This incident is quoted merely to stress on a key takeaway i.e., 'Prompt decision making is important'. Hence, this is not the correct answer.
Option B: Prompt decision making is mentioned as one of the important qualities which a leader must have. However, this passage does not talk further about other qualities which are required in a leader. Hence, option B is incorrect.
Option D: Saying 'yes or 'no' is applicable not only for decision making. A 'yes' or ' a no' can be the answer for any other question unrelated to decision making as well. Hence, option D is incorrect.
