The following script is already saved on MATLAB with its function "exp$29"$ in the same folder.

$t0=0$:$0\mathrm{.}01$:$40$

$x0=[0\mathrm{.}010\mathrm{.}1]$;

$[t,x]=$ ode$45(\text{'}exp29\text{'},t0,x0)$

plot $(t,x($:$,1),t,x($:$,2))$

The error in this script is:

Select one:

a$.$ None of these

b$.$ write $xO=[0\mathrm{.}01$;$0\mathrm{.}1]$ and not $0=[0\mathrm{.}010\mathrm{.}1]$

c$.$ write plot$(t,x(1,$:$),t,x(2,$:$))$ instead of plot$(t,x($:$,1),t,x($:$,2))$

d$.$ No error

e$.[t,x]=0$ de$45(\text{'}$exp$29\text{'},t0,x0)$ is wrongly written
