Hey there mate ☺️,
Option B will be your correct answer.
Proof:-
This so because, Let's consider the red colour as Hydrogen and white colour as oxygen.
Given,
Hydrogen = 2
Oxygen = 2
So, the only image which satisfies the given condition, or the image that shows two white coloured balls and two red colored balls is the Option B image. Other all differ from each other.
