D. 1/2
E. 2/3

Solution:
• The shape of the tank is cubical
o It means $$l = b = h= x$$ (say)
• Now, as water is poured in the tank, the length and breadth of the tank will remain same and height of water in the tank will vary as we pour water in the tank
• It is given that tank is filled up to $$2$$ feet and water occupies $$18$$ cubic feet.
o It means $$x*x*2 = 18$$
 $$x^2 = 9$$
 $$x = 3$$
• Now, volume of the tank = $$x*x*x = 3*3*3 = 27$$ cubic feet.
• It is given that water in tank occupies $$18$$ cubic feet.
o The fraction of capacity which is filled with water = $$\frac{18}{27}=\frac{2}{3}$$
Hence, the correct answer is Option E
