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.

Sliding filament theory can be best explained as
1. when myofilaments slide pass each other actin filaments shorten while myosin filament do not shorten
2. actin and myosin filaments shorten and slide pass each other
3. actin and myosin filaments do not shorten but rather slide pass each other
4. when myofilament slide pass each other myosin filament shorten while actin filaments do not shorten
