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 :

X = 12, Y = 7
True ribs are attached dorsally to vertebral column and ventrally to the sternum

X = 12, Y = 5
True ribs are attached dorsally to vertebral column and sternum on the two ends

X = 24, Y = 7
True ribs are dorsally attached to vertebral column but are free onventral side

X = 24, Y = 12
True ribs are dorsally attached to vertebral column but are free on ventral side

Solution

X = 12, Y = 7
True ribs are attached dorsally to vertebral column and ventrally to the sternum

In human, 12 pairs of ribs are present in which 7 pairs of ribs (1st to 7th pairs) are attached dorsally to vertebral column and ventrally to the sternum
