a. hydrothermal vents

The correct answer is option a. hydrothermal vents. Hydrothermal vents are a type of seafloor feature found along rifts in the mid-ocean ridges.

To arrive at the answer, you can use a couple of strategies. One way is to have prior knowledge of the topic. If you are familiar with oceanography or geology, you may already know that hydrothermal vents are typically associated with mid-ocean ridges.

Another way to approach it is through process of elimination. You can quickly rule out options b, c, and d since maganese nodules, deep sea trenches, and seamounts are not commonly found along rifts in mid-ocean ridges.

If you are unsure about the term "hydrothermal vents," you can also employ a search engine to find more information on this topic. Searching for "seafloor features along mid-ocean ridges" will likely lead you to information about hydrothermal vents and their association with the geological activity in those areas.
