Goitre disease is common in people living in hilly areas hilly whose main symptom is swollen thyroid gland in neck part. But goitre doesn't influence the probability of myxoedema or Grave's disease. Myxedema is advanced hypothyroidism which occurs when body doesn't produce enough thyroid hormone. Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactive thyroid. So, option b is correct.

Explanation:
The correct answer is option B, i.e., Statement ii) is wrong and i) is correct. Let's understand why.
Goitre and its Causes:
- Goitre is a condition characterized by the enlargement of the thyroid gland, which is located in the neck.
- It is primarily caused by iodine deficiency in the diet, leading to the inability of the thyroid gland to produce sufficient amounts of thyroid hormones.
- Iodine is an essential mineral required for the synthesis of thyroid hormones, namely thyroxine (T4) and triiodothyronine (T3).
- In areas where there is a lack of iodine in the soil and drinking water, people are prone to iodine deficiency and subsequent development of goitre.
Statement i) is correct:
- In the given scenario, Shekhar, a 3-year-old child living in hilly areas, has a swollen neck. This swelling is characteristic of goitre.
- The swelling occurs due to the enlargement of the thyroid gland in an attempt to compensate for the low levels of thyroid hormones.
- Iodine deficiency is a common cause of goitre, especially in regions where the soil lacks iodine, such as hilly areas.
- Therefore, statement i) is correct, as Shekhar's swollen neck is likely due to goitre caused by iodine deficiency.
Statement ii) is wrong:
- Statement ii) suggests that goitre may lead to myxoedema and Graves' disease in the future. However, this statement is incorrect.
- Myxoedema is a condition characterized by severe hypothyroidism, where the thyroid gland fails to produce adequate thyroid hormones.
- Graves' disease, on the other hand, is an autoimmune disorder where the thyroid gland is overactive, resulting in excessive production of thyroid hormones.
- While goitre is a physical manifestation of thyroid dysfunction, it does not directly lead to myxoedema or Graves' disease.
- Myxoedema is typically caused by long-term, untreated hypothyroidism, and Graves' disease is an autoimmune condition with its own specific causes.
- Therefore, statement ii) is incorrect.
Conclusion:
In conclusion, Shekhar's swollen neck is likely due to goitre caused by iodine deficiency, which is a correct statement (i). However, the statement suggesting that goitre may lead to myxoedema and Graves' disease in the future is incorrect (ii).
