Heterochromia is an anomaly that people and some animals may have where the irises are of different colors. On several occasions, heterochromia can affect the hair or skin, but it is more common to see people with this abnormality in the eyes.
It is normal to see some animals with this condition, especially cats. The fact that a cat has heterochromia does not mean that its life is going to be in danger, nor does it hinder its ability to see. The animal may develop this anomaly due to some disease that has suffered in its ocular or congenital area. No matter the breed of the cat, anyone has the possibility of having heterochromia.
I think its D. to advance because the affix on immovable is <em>im</em> and if you take that off you <em>IM</em> movable which clearly means able to move or advance. HOPE THIS HELPED!!!
