Solution

The correct option is D 2L
When the two inductors are connected in series to one another, they are simply been added up and the direction of the magnetic flux does not have any affect on the net inductance of the two inductors.

$L^{'} = L_{1} + L_{2}$

$L^{'} = L + L$
$L^{'} = 2 L$

So, option $C$ is correct.
