Solution
The correct option is B IgG
A newborn does not yet have a mature immune system and is often unable to mount an effective immune response. There are three main immunoglobulins, IgG, IgA and IgM, and of these only IgG is small enough to cross the placental barrier. It affords immunity to specific viral infections. At birth the baby's levels of IgG are equal to or slightly higher than those of the mother. This provides passive immunity during the first few months of life.
