What model year did the emission system begin to be installed by manufacturers?

  1. 1950

  2. 1968

  3. 1975

  4. 1990

The correct answer is: 1968

During the late 1960s, the United States government began to focus on reducing harmful emissions from vehicles. This led to the introduction of the first emission control devices in 1968. Prior to this, vehicles did not have any regulations on their emissions, which is why options such as A, C, and D are incorrect. 1950 is too early for the introduction of emission systems, and options C and D are too late as emission control devices were already well-established by then. Therefore, B (1968) is the most accurate and logical answer.
