In the question given below, a passage is followed by three statements. Select the correct combination of statements that can be inferred from the passage. Passage: A recent study suggests that children who grow up with pets tend to have stronger immune systems and are less likely to develop allergies. Exposure to pet dander and microbes in early childhood may help build immunity. However, this does not guarantee protection from all illnesses and some children may still develop allergic reactions despite early exposure. Statements:
I. Children exposed to pets early in life are guaranteed to never develop allergies.
II. Early exposure to pet-related microbes may contribute to stronger immunity in children.
III. There are exceptions to the idea that pet exposure reduces allergies.
