Vedclass · Answer

(A) The stages of human embryonic development occur as follows:$a$. Fully formed morula: The morula stage is reached by the end of the $4^{	ext{th}}$ day after fertilization $(a-iii)$.$b$. Fully formed blastocyst: The blastocyst is fully formed by the end of the $7^{	ext{th}}$ day after fertilization $(b-i)$.$c$. Completion of implantation process: Implantation is generally completed by the end of the $10^{	ext{th}}$ day after fertilization $(c-iv)$.$d$. Fully formed gastrula: Gastrulation begins and proceeds,with the formation of the three germ layers typically becoming distinct around $15$ days after fertilization $(d-ii)$.Therefore,the correct matching is $A-III, B-I, C-IV, D-II$.

Column $I$	Column $II$
$a$. Fully formed morula	$i$. By end of $7^{\text{th}}$ day after fertilization
$b$. Fully formed blastocyst	$ii$. $15$ days after fertilization
$c$. Completion of implantation process	$iii$. By end of $4^{\text{th}}$ day after fertilization
$d$. Fully formed gastrula	$iv$. By end of $10^{\text{th}}$ day after fertilization

Column-$I$	Column-$II$
$A$. $1^{st}$ month	$i$. First movement of foetus
$B$. $2^{nd}$ month	$ii$. Major organ system
$C$. $3^{rd}$ month	$iii$. Foetal heart
$D$. $5^{th}$ month	$iv$. Limbs $\&$ digits
