How Does the Angular Resolution of the 305-M Arecibo Radio

Multiple Choice

How does the angular resolution of the 305-m Arecibo radio telescope in Puerto Rico compare with the angular resolution of the 10-m Keck optical telescope on Mauna Kea,Hawaii?

A) It is not possible to compare their angular resolution because they work in different wavelength ranges.
B) The 305-m Arecibo telescope has much better angular resolution than the 10-m Keck telescope.
C) They have about the same angular resolution because angular resolution is limited by turbulence in Earth's atmosphere, not by mirror diameter.
D) The 305-m Arecibo telescope has much worse angular resolution than the 10-m Keck telescope.
