Answer 1

The correct option is A A- r, B- t, C- s, D- p

Klinefelter syndrome is the presence of one or more extra chromosomes in a male (44+XXY). Turner's syndrome is the absence of one X-chromosome from female (44+XO). Super female is characterized by the presence of extra one X-chromosome in female (44+XXX). Patau's syndrome is trisomy 13; characterized by the presence of three copies of chromosome 13 instead of the usual two. Hence, the correct answer is option A.
