The scale factor of viewport transformation for x co-ordinate is ________

(a) Sy = (svmax + svmin)/ (swmax + swmin)

(b) Sy = (svmax – svmin)/ (swmax + swmin)

(c) Sy = (svmax – svmin)/ (swmax – swmin)

(d) Sy = (svmax + svmin)/ (swmax – swmin)

The question was asked in an international level competition.
