Out of ' \(X\) ' pairs of ribs in humans only ' \(Y\) ' pairs are true ribs. Select the option that correctly represents values of \(\mathrm{X}\) and \(\mathrm{Y}\) and provides their explanation:
1 \(\mathrm{X}=12, \mathrm{Y}=5\) True ribs are attached dorsally to vertebral column and sternum on the two ends.
2 \(X=24, Y=7\) True ribs are dorsally attached to vertebral column but are free on ventral side
3 \(X=24, Y=12\) True ribs are dorsally attached to vertebral column but are free on ventral side
4 \(X=12, Y=7\) True ribs are attached dorsally to vertebral column and ventrally to the sternum.
Explanation:
\({\rm{X = 12}}\) (ribs in human) \(\mathrm{Y}=7\) ( true ribs) There are 12 ribs in humans, among which first 7 are true ribs, which is attached to vertebral column dorsally and ventrally to sternum.
