true........d is the correct answer....hypothyroidism(cretinism) in children is characterized by hypothermia,feeding problems,persistent jaundice,umblical hernia,protruding tongue,spasticity,failure to thrive,stunted bone growth,mental retardation........and low circulating levelz of THYROID HORMONES will cause increased TSH levels which will cause thyroid hyperplasia......
