Suppose you have two small photographs of the Moon. Although both look the same at small size, when you blow them up to poster size one of them still looks sharp while the other one becomes fuzzy (grainy) looking. Which of the following statements is true?
A) The one that still looks sharp at large size has better (smaller) angular resolution than the one that looks fuzzy.
B) The one that looks fuzzy at large size has better angular resolution (smaller) than the one that looks sharp.
C) Both photographs have the same angular resolution, because they were both printed at the same sizes in each case.
