203 28. For a posit, o Eor a Dositive real number a, let Sa denote the set of points (r, y) satisfying +Il=1. A positive number a is said to be good if the points in S that are closest too the origin lie only on the coordinate axes. Then (A) all a in (0,1) are good and others are not good. (B) all a in (1,2) are good and others are not good. (C) all a> 2 are good and others are not good. all a>1 are good and others are not good.
