Posted under IC22 Life Insurance Underwriting

Answer: (b).Equalize pressures on both sides of the ear drum Explanation:The eustachian tube connects the middle ear to the nasopharynx and helps in the equalization of pressures on both sides of the ear drum. This tube allows air to enter the middle ear cavity, which helps to balance the pressure on both sides of the eardrum and prevent damage to the hearing mechanism.
