Question

Quizplus · Accepted Answer

The highest resolution attainable by Very Long Baseline Array (VLBA) is 0.001 arcsec, which is achieved by combining signals from radio telescopes on opposite sides of Earth. This is possible due to the technique of interferometry, where multiple telescopes are used to capture and combine signals from a single object, improving the resolution of the resulting image. Thus, option B is the correct answer.
