The spring force is given by $F=-kx$, where $k$ is a constant and $x$ is the deformation of spring. The $F-x$ graph is:

A parallelogram $ABCD$ is shown in the figure.

Correct matching is

If a particle starts moving along $x-$axis from the origin with initial velocity $u=1 \mathrm{m} {\mathrm{s}}^{-1}$ and acceleration $a=2 \mathrm{m} {\mathrm{s}}^{-2}$, the relationship between displacement and time is,
$x=ut+\frac{1}{2}a{t}^2=1\times t+\frac{1}{2}\times 2\times t^2=t+t^2$.
Draw the displacement$\left(x\right)$-time$\left(t\right)$ graph.
