Answer
Brief Explanations:
Konstantin Tsiolokovsky proposed the concept of multistage rockets in 1903. In his work "Exploration of Cosmic Space by Means of Reaction Devices" published in that year, he laid out important theoretical foundations for rocket technology, including ideas related to multistage rockets which help in achieving higher velocities and reaching space more effectively by shedding unnecessary mass (empty stages) during flight. 1969 is known for the Apollo 11 moon landing, and 1887 is an earlier year when his work was likely in earlier development phases but not the year of the multistage rocket concept proposal.
Answer:
1903
