(B) In the development of an embryo,the oospore (zygote) undergoes its first division to form two cells: a basal cell and a terminal cell.If the embryo develops from the cell that is towards the inner side (micropylar or chalazal depending on the orientation) and the suspensor develops from the cell towards the outer side,the orientation is termed as endoscopic.In endoscopic development,the apex of the embryo is directed towards the interior of the embryo sac.Therefore,the correct term for this type of development is endoscopic.

Column-$I$	Column-$II$
$a$. Suspensor initial	$i$. Large basal cell of the $2$-celled pro-embryo
$b$. Embryonal initial	$ii$. First cell of the suspensor towards micropylar end
$c$. Haustorium	$iii$. Lowermost cell of the suspensor
$d$. Hypophysis	$iv$. Small terminal cell of $2$-celled pro-embryo

When the inner half of the oospore after the first division develops into an embryo and the outer half develops into a suspensor,this type of development is called:
