$A$ student plots a graph from his readings on the determination of Young's modulus of a metal wire but forgets to label the axes. The quantities on $X$ and $Y$ axes may be respectively:

The stress-strain curves are drawn for two different materials $X$ and $Y$. It is observed that the ultimate strength point and the fracture point are close to each other for material $X$ but are far apart for material $Y$. We can say that materials $X$ and $Y$ are likely to be (respectively)

$A$ stress-strain graph for a metal is shown. The part in which Hooke's law holds good is

Two different types of rubber are found to have the stress-strain curves as shown. Then:

The diagram below shows the change in the length $X$ of a thin uniform wire caused by the application of stress $F$ at two different temperatures $T_1$ and $T_2$. The variation shown suggests that

The diagram shows a force-extension graph for a rubber band. Consider the following statements:
$I.$ It will be easier to compress this rubber than expand it.
$II.$ Rubber does not return to its original length after it is stretched.
$III.$ The rubber band will get heated if it is stretched and released.
Which of these can be deduced from the graph?
