Explanation / Answer

Scenario 1 is not dangerous, eventually if a person is not lactose intolerant then lactose will
break down to form glucose and galactose. It is the absence of enzyme that makes lactose intolerant
hence the answer.
Scenario 2 cannot be dangerous, a lactose intolerant person with galactosemia cannot break down lactose
into galactose in the first place.
Scenario 3 can be pretty dangerous because the lactose tolerant person with galactosemia
can break down lactose to galactose but will not be able to degrade galactose i.e) either partially
or not all which can cause convulsions and other symptoms. A person with Galactosemia should
avoid galactose.
Hence Scenario 3 is the most dangerous.
