option D is the ans as statement III is incorrect

First two statements are correct


A spaceball is a "six degrees of freedom" device. It allows full rotation in multiple directions, such as with a CAD model. a trackball, however is merely a standard mouse. rather than having the ball moved by the mouse platform, you manually actuate the ball. it just moves the cursor around. the libsball page has a nice image showing the spaceball's range and type of motion. a trackball just does XY axis motion.
