The answer is; C
As can be observed in the diagram, the oceanic plate of the crust is being subducted by the continental plate. This is typical of a subduction zone where two tectonic plates, moving in opposite directions, collide. The heavier plate (usually the oceanic plate due to its ‘wetness’) sinks below the lighter plate (usually the continental plate). An example of a subduction zone is the famous ‘ring of fire’ region in the Pacific.
Answer:
<h2>when metallic oxides react with water they form metallic hydroxides which are basic in nature.to show that these are basic in nature,we should conduct a litmus paper test.in this experiment,we will observe that red litmus turns blue on coming in contact with them. this shows that metallic oxides are basic in nature</h2>
It can be either C or B
Reasons it can be C: Red and Blue together(if I'm correct in art) is the combined color of two of the 3 primary colors to get a purple/violet color and if said filter is see through or just too dense for the light to even penetrate the said filter(in theory) but all in all purple is the answer with the two primary colors blue and red.
But also, it depends on what kind of filter it is, if the filter is like a screen filter then it will just come out in blue with the slightly different colors of again purple but in a darker tone then the actual eye can see.
Or it can be just C again cause the filter can be a film but that's a bit too far and to complex for right now so I believe it is B
