In the following code, please note the missing sections labeled $?1,?2$ and $?3.$

function $[$final$]=$ examQuestion $($mat$)$

$[$m$,$n$,$~$]=$ size$($mat$)$;

final $=$ uint$8($zeros$(?1))$;

for i $=?2$

if mod$($i$,2)==1\%$ odd index

for j $=1$:n

final$($i$,$j$,1)=$ mat $(($i$+1)/2,$j$,1)$;

final$($i$,$j$,2)=$ mat $(($i$+1)/2,$j$,2)$;

final$($i$,$j$,3)=$ mat $(($i$+1)/2,$j$,3)$;

end

$?3\%$ even index

for j $=1$:n

final$($i$,$j$,1)=$ mat $($i$/2,$j$,1)/2+$ mat $($i$/2+1,$j$,1)/2$;

final$($i$,$j$,2)=$ mat $($i$/2,$j$,2)/2+$ mat $($i$/2+1,$j$,2)/2$;

final$($i$,$j$,3)=$ mat $($i$/2,$j$,3)/2+$ mat $($i$/2+1,$j$,3)/2$;

end

end

end

The final image is supposed to be extended along the vertical direction by inserting new row as average of neighboring rows. Which of the following should replace the missing sections?

Group of answer choices

$?1$ should be $(2*$m$-1,$n$,3),?2$ should be $1$:$2*$m$-1,?3$ should be else

$?1$ should be $($m$,2*$n$-1,3),?2$ should be $1$:m$,?3$ should be end

$?1$ should be $(2*$m$-1,2*$n$-1,3),?2$ should be $1$:$2*$m$-1,?3$ should be elseif mod$($i$,2)==0$

$?1$ should be $(2*$m$-1,$n$,3),?2$ should be $1$:m$,?3$ should be elseif
