In Column$-I$ there are two graphs and in Column$-II$ whose graph is for this are given. Join them appropriately :

Column $-I$	Column $-II$
$(a)$ image	$(i)$ $A$ is ductile
$(b)$ image	$(ii)$ $A$ is brittle
	$(iii)$ $B$ is ductile
	$(iv)$ $B$ is brittle

The stress-strain graphs for materials $A$ and $B$ are shown in Figure

The graphs are drawn to the same scale.

$(a)$ Which of the materials has the greater Young’s modulus?

$(b)$ Which of the two is the stronger material?

The graph is drawn between the applied force $F$ and the strain $(x)$ for a thin uniform wire. The wire behaves as a liquid in the part

The stress versus strain graphs for wires of two materials $A$ and $B$ are as shown in the figure. If ${Y_A}$ and ${Y_B}$ are the Young ‘s modulii of the materials, then

Stress vs strain curve for the elastic tissue of the aorta, the large tube (vessel) carrying blood from the heart, will be : [stress is proportional to square of the strain for the elastic tissue of the aorta]

The stress versus strain graphs for wires of two materials $A$ and $B$ are as shown in the figure. If $Y_A$ and $Y_B$ are the Young's modulus of the materials, then
