The correct answer is option 2: Singapore. Eator is a fictional location, so it does not have a physical proximity to any real city. The question is asking which of the given cities is the closest to Eator, and Singapore is chosen as the closest option among the given cities. However, it is important to note that this answer is based on the options provided and not on any specific geographical information. Therefore, it is essential to carefully read and understand the context of the question before selecting an answer.

In this case, since Eator is a fictional location, it is not possible to determine the actual closest city. It is important to pay attention to such details in questions and not assume any real-world correlation unless explicitly stated.
