    Here project is in early stages of planning means not much of detailed and precise data available. Client asks for high level estimate of duration as soon as possible. Here high level means initial estimate , can say ROM. not very accurate and which less costly and less time-consuming . so we use analogous estimating base on historical data of similar project. pl refer section 6.4.2 PMBOK 6 for further insights.

    To add to Arvind's comment, when do we use 3-point estimates, instead of High-level or Definitive? It's when "... there is insufficient historical data or when using judgmental data..." (p. 201). You'll also see this as a correct option when you are looking for a range and probability, instead of a single-point estimate. If you see a comment like those in the scenario / question, three-point estimates are a good choice.
