A cube is painted blue on two adjacent surfaces and black on the surfaces opposite to blue surfaces and green on the remaining faces .Now the cube is cut into 216 smaller cubes of equal size.

As per the given above question figure ,
Figure ( 4 ) of the answer figures is exactly the water image of the given original image . Thus , Given image will become opposite in water across the given line.So , option D is correct figure .

On the basis of above given question , we have
The mirror image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Hence , required answer is option A.

As per the above given question , we can say that
Water image is the reflection of an object into the water . It appears by inverting an object vertically i.e. upside down. The water image always be opposite the original image across the given line. It will become opposite to the given line .
Thus , required answer will be option A .

As we know that the water image always be opposite the original image across the given line. It will become opposite to the given line .As shown in given below .
Hence , option B is required answer .

Upper part will go down in opposite direction in water image.
