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.
