To determine the future positions of the star and triangle based on the movement of tectonic plates that form mountains, we need to consider how tectonic plates interact, especially at convergent boundaries.
If the star and triangle are points on two plates moving toward each other, they will likely move closer together over time, leading to the formation of mountains.
Without the specific visual diagram referenced in your question, it is difficult to provide an exact answer. However, if the options represent locations they may move toward based on a typical convergent plate boundary scenario, you would select the location that indicates movement toward each other.
In summary, if you know the direction the plates are moving and what locations A, B, C, D, and number 1, 2, 4 refer to, you could deduce where the star and triangle will end up. Generally, they'd be at points that are closer together than before, ideally at locations where the mountain-building process is occurring.
Please check the diagram for the exact positions or the movement directions to select the right answer among the options provided.
