Answer 1

Answer:

I think option 3 is the correct answer.

as for the 1st option 8th 9th and 10th ribs are attached to the sternum by cartilages.

the 2nd option is wrong because 11th and 12th pair of ribs are floating ribs and are not articulated.

and for the 4th option i am not sure but id think its correct.

Hope it helps..
