Straight away it can't be A or B because the last/ones digits aren't multiples of 5.
For something to be divisible by 9, add all the digits up and see if it is a multiple of 9:
This works for both C and D, as both numbers have digits which add up to 18.
However, only C is divisible by 6. D is an odd number and hence it is eliminated. For something to be divisible by 6, it must be divisible by 2 (an even number) and 3 (digits add to a multiple of 3). C does both.
Hence C is the answer.

Answer:
The height of the water is 
Step-by-step explanation:
step 1
Find the volume of the tank
The volume of the inverted right circular cone is equal to

we have


substitute


step 2
Find the 25% of the tank’s capacity

step 3
Find the height, of the water in the tank
Let
h ----> the height of the water
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional

substitute

where
r is the radius of the smaller cone of the figure
h is the height of the smaller cone of the figure
R is the radius of the circular base of tank
H is the height of the tank
we have
-----> volume of the smaller cone
substitute

Simplify
