Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.
The red light would be absorbed by the green object and the object would appear dark. The green object reflects green light and absorbs other colors.
The green object will appear black because it will not reflect any of the blue light shone on it. Green objects primarily absorb blue light, so without any green or red light present, the object will appear dark.
The yellow object will appear dark because it reflects yellow light, which is a combination of red and green light. Since only red light is being shone on it, the object will not reflect any light and will appear black.
A cyan object will appear black when only magenta light is shone on it. Cyan objects absorb magenta light, so no light is being reflected back to our eyes, causing the object to appear black.
Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black. It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.

To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.
