If u = {all positive integers) and a = {x|x eu and x is an odd positive integer}, which describes ac? aº = {xlx eu and is a negative integer} ac = {x|x eu and is zero} aº = {x|x eu and is not an integer} aº = {xlx eu and is an even positive integer}

So last choice.   (Also I assume AC meant the complement of A)
