Solution
The correct option is C Goitre
Goitre is an 'endemic disease', i.e. a disease which is restricted to only particular regions- the regions in this case being hilly regions, which are at a distance from the sea-coast. This is because the soil in these hilly areas does not contain much iodine, and hence the food grown and water drunk is devoid of iodine. In contrast, in areas near the sea-coast, marine-fish and other sea-food is consumed, which are rich in iodine, as a result of which goitre is seldom heard of in those parts.
