The correct answer is D. promise.
The word “promise” means to make a declaration or assurance that one will do or refrain from doing something. In this case, the project did not appear to be likely to be successful. This could be because the project was poorly planned, the team was not experienced, or the resources were not available.
The other options are not as accurate. The word “highlight” means to draw attention to something. In this case, the project did not appear to have any positive aspects. The word “show” means to make something visible or known. In this case, the project did not appear to have any potential. The word “offer” means to present something for acceptance or rejection. In this case, the project did not appear to be worth pursuing.
