Match Column-$I$ with Column-$II$ and select the correct option.

Column-$I$	Column-$II$
$(a)$ Thylakoids	$(i)$ Disc-shaped sacs in Golgi apparatus
$(b)$ Cristae	$(ii)$ Condensed structure of $DNA$
$(c)$ Cisternae	$(iii)$ Flat membranous sacs in stroma
$(d)$ Chromatin	$(iv)$ Infoldings in mitochondria

$DNA$ is not present in which of the following?

Identify the correct statements w.r.t. the given cell diagram:
$A$. Concerned with lipid and steroidal hormone synthesis.
$B$. Outer non-living rigid structure which gives shape to the cell and protects from mechanical damage and infection.
$C$. Both lie perpendicular to each other and each has an organisation like the cart wheel.
$D$. Responsible for trapping light energy for the synthesis of sugar.
$E$. Present in cells actively involved in protein synthesis and secretion.
$F$. Spherical structures,rich in hydrolytic enzymes.

Column-$I$ represents the organelle and Column-$II$ represents its structure. Select the correct option:

Column-$I$	Column-$II$
$(A)$ Mitochondria	$(i)$ Single membrane-bound structure
$(B)$ Lysosome	$(ii)$ Non-membrane-bound structure
$(C)$ Nucleolus	$(iii)$ Double membrane-bound structure
