A.We need to know their orbital periods.

B.We need to know whether either moon is volcanically active.

C.We need to know whether the planet also has a third moon.

D.No other information is needed: With two moons, there is sure to be tidal heating.

E.No other information is needed: With two moons, there is no chance of any tidal heating.
