(1 alone) Does not tell you anything about the size of the tank. OUT

(2 alone) Does not tell you anything about the rate of leakage. OUT

(1 & 2) Lets do some simple math to begin.

30 gallons = 3840 oz
6.4 oz/min = 384 oz/hr

Ah, nice! 3840 and 384 are easy numbers to work with. It should be pretty clear that...

10 hours to drain => 30 gallons
less than 10 hours to drain => less than 30 gallons
more than 10 hours to drain => more than 30 gallons

However, (2) does not help us out in this category, as the time could be either 1 or 11. OUT

(1 or 2) OUT

(Neither Sufficient) CORRECT

E as well.
1 is clearly not sufficient.
2 Without knowing rate of leakage nothing can be said. - not sufficient.

1+2 at 6.4 ounce per min in 12 hours 36 gallons will be leaked so if tank leaks in 11:59 hrs tank must have > 30 gallons initially. This case yields "yes" answer. but if the tank is empty in 2 hours then tank has 6 gallons which is < 30. This case yields "no" answer. NOT SUFFICIENT.
