Select the correct option. Physicist Robert H. Goddard of Clark University was the creator of the technology used by modern rockets (those that are powered by liquid fuels and not by gunpowder). In a Smithsonian Institute publication, the professor said that the rockets would serve, in addition to transporting meteorological measurement equipment beyond the Earth's atmosphere, to travel to the Moon. Due to this, on January 13, 1920, a review "A severe strain on credulity" was published in the "Topics of the Times" of the New York Times, where the possibility of the operation of the rocket outside the Earth's atmosphere is questioned since without a resisting atmosphere, the propulsion engines could not fly, thus mocking Professor Goddard's knowledge. The New York Times published 49 years later (on July 17, 1969, when the Apollo 11 astronauts headed for the Moon): "The Times regrets the mistake." That error was due to the fact that the New York Times considered that: A) would receive a force of the same magnitude but in the opposite direction to that of the gases B) it would not receive momentum since it would not have a medium on which the gases interact c) in space the laws of dynamics can be applied to gases as well D) changes in the momentum of the rocket and gases occur
