Astronomers found stars careening around these centers, zooming at previously unheard-of speeds in their orbits. The motion was

You might be able to guess what this was, but for scientists, the best answer came as a shock. In 1994 telescopic evidence confirmed the amazing cause: a supermassive black hole, with the mass not of one imploded star, not of two, but of millions – maybe even billions.

Which connection helps the reader understand how supermassive black holes were found?
Answer:
Astronomers and telescopic evidence
Explanation for answer:
Since the passage given that Astronomers found stars careening around these centers, zooming at previously unheard-of speeds in their orbits and telescopic evidence confirmed the amazing cause: a supermassive black hole, with the mass not of one imploded star, not of two, but of millions – maybe even billions.
Thus, base on the given we can know that telescopic evidence confirmed the amazing cause: a supermassive black hole so the only answer with telescopic evidence and astronomers is [B] astronomers and telescopic evidence
