Correct Answer
(A) Down's syndrome
Solution & Explanation
Answer: (A) Down's syndrome Solution: A broad palm with a single (characteristic) transverse palm crease is a classic feature of Down's syndrome (trisomy of chromosome 21), along with short stature, small round head, furrowed tongue and partially open mouth. Turner's, Klinefelter's and thalassemia do not present this palm crease, so Down's syndrome is the answer. NCERT Reference: NCERT Class XII, Ch 4, p.76, lines 23-25: "The affected individual is short statured with small round head, furrowed tongue and partially open mouth (Figure 4.16). Palm is broad with characteristic palm crease."
