Yes, the sentence with incorrect subject-verb agreement is option D: "Since that time, South Korea's economy, which follows the capitalistic model and enjoys the opportunities that come with free enterprise systems, have been growing steadily."

To determine the correct subject-verb agreement, you need to identify the subject of the sentence and ensure that the verb agrees with it in number (singular or plural).

In this case, the subject is "South Korea's economy," which is singular. Therefore, the verb should be in the singular form. However, in option D, the verb "have been" is in the plural form, which is incorrect. It should be "has been" to match the singular subject.

To find the answer to this question, you need to analyze each sentence and consider whether the subject and verb match in number. In this case, option D contains the incorrect subject-verb agreement.
