Heart ,artery and veins as you all know are parts of circulatory system . Thus, there is no odd one out in group X. Brain and spinal cord run your nervous system and liver helps in the digestive system . Kidney , skin and even lungs are part of excretory system so group Z is clear .Thus , option 'C' liver is the odd one out as it cannot be placed in group Y .
