I think C is correct answer
(1) only tells nothing
(2) if less than half of the tank has been filled so the tank is being filled
but if more than half of the tank has been filled so the tank is being emptied.
(1,2) together we can say that the level of water remains the same after every hours.
But i feels this quest still a controversal one.

V =cap. of tank
Vc = current water in tank

S1: V = 10lts, Vc = 5lts

Not sufficient.

S2:
Rleak = 0.1 x Vc

Not sufficient.

S1 & S2:
V = 10lts, Vc = 5lts
Rleak = 0.1 x 5 = 0.5 lts/hr

Radd = 0.1 x 5 = 0.5 lts/hr

As Radd = Rleak not being emptied or being filled.

I would go for E.
