Read the following information carefully and answer the question that follows. You must assume everything in the statement to be true and decide which of the conclusion/s logically follow/s.

Infant jaundice is yellow discoloration of newborn baby's skin and eyes which occurs because the baby's blood contains an excess of a yellow pigment called bilirubin. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream.

Which of the following can be concluded from the given information?

A. In some newborn babies suffering from jaundice, the liver is not fully developed which causes excess bilirubin in the blood.

B. The function of liver is also to remove excess bilirubin from the blood.

C. Excess bilirubin is undesirable for infants only. For adults, bilirubin is necessary for survival.

D. The colour of an infant's skin and eyes is usually yellowish in colour.​​

Given: 

Infant jaundice is yellow discoloration of newborn baby's skin and eyes which occurs because the baby's blood contains an excess of a yellow pigment called bilirubin. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream.

A.  In some newborn babies suffering from jaundice, the liver is not fully developed which causes excess bilirubin in the blood.
 Does NOT follow. The passage says jaundice usually occurs due to immature liver, not that “some” specific subset of infants definitely have this issue.

B. The function of liver is also to remove excess bilirubin from the blood.

The passage says jaundice occurs because the baby’s liver isn’t mature enough to get rid of bilirubin — implies this is a function of the liver. So this is → true.​

C. Excess bilirubin is undesirable for infants only. For adults, bilirubin is necessary for survival.

This is not stated or implied. The passage only talks about infants, and says nothing about bilirubin's effect or necessity in adults. So this is → not a valid conclusion.​

D. The colour of an infant's skin and eyes is usually yellowish in colour.​​

The passage says this happens in case of jaundice, not usually for all infants. So this is a wrong generalization → not valid.​​

From the given options, option (c) is correct. Because A and B both are not given in options.

So, only B is true.

Thus, correct option is (c).
