Final answer:
The objection about needing time to think over a decision is best handled by asking the individual to specify their concerns, allowing for targeted discussions to address these issues.
Step-by-step explanation:
The objection related to the need for time to think over a decision is addressed directly by option B: "I can appreciate that, making a logical decision is important... so tell me, what is it specifically that you're going to have to think over?" This response encourages the individual to articulate their specific concerns, which can then be addressed in a targeted manner, rather than allowing a vague objection such as needing more time to stall the decision-making process. By pinpointing the exact issues, the concerned party can be provided with the necessary information to feel more comfortable and make an informed decision. This approach to handling objections is crucial for decision-making in various contexts, whether it be in a workplace setting, personal decision-making, or high-stakes environments like buying a car, where careful consideration and understanding of opportunity cost and thinking at the margin play pivotal roles.
