Out of 'X' pairs of ribs in humans only 'Y' pairs are true ribs. Select the option that correctly represents values of X and Y and provides their explanation.

(1) X = 12, Y = 7           True ribs are attached, dorsally to 

                                      vertebral column and ventrally to

                                      the sternum.

(2) X = 12, Y = 5           True ribs are attached dorsally to

                                      vertebral column and sternum on

                                      the two ends.

(3) X = 24, Y = 7           True ribs are dorsally attached to

                                      vertebral column, but are free on

                                      ventral side.

(4) X = 24, Y = 12         True ribs are dorsally attached to 

                                      vertebral column, but are free on 

                                      ventral side.

The pivot joint between atlas and axis is a type of
