D is the right answer.

To determine the correct answer, we need to analyze the given information and eliminate the wrong options.

Option A states that the visit led to the implementation of the two-child policy in China. However, the two-child policy was not implemented until 2016, so this option is incorrect.

Option B suggests that the visit resulted in the election of Deng Xiaoping in China. However, the visit of the nuclear physicist did not directly lead to Deng Xiaoping's election, so this option is also incorrect.

Option C implies that the visit led to the implementation of new nuclear-power safety measures in populated areas in China. While it is plausible that the visit may have influenced such measures, it is not explicitly stated in the given information. Therefore, this option cannot be confirmed as the correct answer.

Option D states that the visit resulted in the implementation of the one-child policy in China. From the information provided, we cannot directly confirm or rule out this option. However, considering that the one-child policy was implemented in China starting from 1979, it is the most likely outcome based on the information given.

Therefore, based on the given options, option D, the implementation of the one-child policy in China, is the most likely correct answer.
