Concepts: Circular orbits, Conservation of angular momentum, Elliptical orbits

Solution:

By conservation of angular momentum, each satellite has the same angular momentum at any point along its orbit. Thus, we can shift point A to coincide with the apogee of the ellipse and point C to coincide with the perigee of the ellipse.

Recall the velocity of a circular orbit is

The angular momentum is then

Since $r_A>r_C$, we have $L_A>L_C$. At the apogee, the velocity $v_B$ of satellite $B$ is smaller than the velocity $v_A$ of satellite $A$ since the ellipse is contained in the $A$ circle. Thus, we have $L_B<L_A$. Similarly, we find $v_B>v_C$ at the perigee since the ellipse contains the $C$ circle. Thus, $L_B>L_C$. Finally, we obtain $L_A>L_B>L_C$ so the answer is A.
