During the Second World War, the United States supported by United Kingdom embarked on developing the first atom bomb which was new-to-the world. The research and development project undertaken for this is known as Manhattan Project. Top nuclear physicists were pulled out from various scientific institutions across the US and UK and were deployed to work full time on the project where they worked in a think tank environment primarily focussing on developing the first atom bomb in a targeted time. Ideally this type of product development requires a. a. Functional-matrix structure b. Functional structure c. Project matrix structure d. Venture structure
