i agree with you but,
in 3, why did you choose USG, the question states that (USG turns out normal)!

in 4, what is the values of the patient being asthmatic? does that affect the answer any how?

carbimazole

How does it work?

Carbimazole is a medicine that is used to decrease the amount of thyroid hormones produced by the thyroid gland. Iodine is a chemical used by the thyroid gland in the formation of thyroid hormones. Iodine must be converted in the body to a useable form before it may be combined with other components to form thyroid hormones. Carbimazole acts to prevent the conversion of iodine to its useable form. Carbimazole also acts to block the combination of converted iodine with other components to form thyroid hormones. This results in a decreased production of thyroid hormones. Therefore, carbimazole is useful in the treatment of conditions where excessive amounts of thyroid hormones are being produced by the thyroid gland (hyperthyroidism). As carbimazole can only decrease the production of thyroid hormones after it is taken, it cannot immediately decrease the blood levels of previously produced thyroid hormones. Previously produced thyroid hormones must be used up by the body before the thyroid hormone blood levels may begin to decrease. This can take three to four weeks
