BLACK.
Yellow-green, or lime.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.

A green object is called "green" because that's the only color of light that it reflects to our eyes, while it absorbs any other light. If there's no green light shining on it, then there's nothing for it to reflect, and we would describe it as a "black" object under those conditions.

White light would be universal, but if you had to choose a color, and the color of the plant is green, then green light would not help it photosynthesize the easiest, because green light is reflected from these plants.
