interpret the slope

In a study of a particular type of fish's feeding habits, zoologists recorded the age (in days) of the fish and the number of aggressive strikes the fish made at the bottom of their aquarium after being given food. Suppose the least squares regression line (equation) to predict the number of aggressive strikes a fish makes based on its age was y-hat =175.70330.82x. Interpret the slope. A) For every one day older a fish gets, its number of aggressive strikes increase, on average, by 0.82 strikes. B) For every additional aggressive strike, a fish's age increases, on average, by 0.82 days. C) For every additional aggressive strike, a fish's age decreases, on average, by 0.82 days. D) For every one day older a fish gets, its number of aggressive strikes decrease, on average, by 0.82 strikes
