Correct answer is option (d).7,3,2
Explanation:
In a man, generally there are 12 pairs of ribs.
The first seven pairs are attached directly to the sternum by costal cartilages and hence, are called the true ribs.
The 8th, 9th, and 10th pairs—were termed as the false ribs, as they do not join the sternum directly but are connected to the 7th rib by cartilage.
The 11th and 12th pairs, were termes as the floating ribs, it is defined as the half the size of the others and do not reach to the front of the body.
Hence, True ribs = 7 pairs, False ribs = 3 pairs, Floating ribs = 2 pairs.
