Step 1: Definition.
Cretinism is a congenital condition caused by iodine deficiency or insufficient thyroid hormone production in early childhood.
Step 2: Symptoms.
Symptoms include stunted physical growth, delayed mental development, hearing impairment, and mutism.
Step 3: Thyroid hormone role.
Thyroid hormones are essential for growth and brain development; deficiency leads to characteristic features of cretinism.
Step 4: Differential features.
Other options describe unrelated disorders (skin, menstrual, intelligence issues), not typical of cretinism.
Step 5: Conclusion.
Hence, the correct answer is stunted growth, mental retardation, deafness, and mutism.
