A rigid motion transformation is a type of transformation whereby all the points of the object is moved from one point to another such that the relative distance and the relative position of the points of the object remain the same.
a)Dicing a carrot changes the size the object not the position of the object.
b)Moving a thermostat control to the right changes the relative position while keeping the shape of the object.
c) Deflating a ballon changes the object not the position.
d) Enlarging is the key word on this one, because it's talking about size, but what we need is the position.
So, the answer is B.
