Answer 1

Hint: Mammary glands produce milk, they are modified sweat glands. It is present in both sexes. Abnormal condition is due to the imbalance caused by increase in the level of oestrogen hormone and simultaneously decreases in the level of testosterone hormone in males.

Complete answer:
Gynaecomastia is an endocrine system disorder in which the size of male breast tissue is increased or we can say proliferation of mammary gland in men.

The development of this condition actually begins in puberty when hormonal changes took place but sometimes it also affects old men due to unusual changes in hormones. It is a unisexual condition and is caused by the presence of extra X in male. Due to the disturbance in the endocrine system it leads to an increase in the ratio of estrogens and androgens are considered to be cause for the development of gynecomastia. The hormones testosterone and estrogen controls characters that decide to be present in either male or female. Testosterone is a male hormone that controls male traits, liked as muscle mass and body hair. Estrogen is a female hormone that controls female traits, such as the growth in breasts size. Gynaecomastia may affect one or both breasts, sometimes unevenly.

Symptoms are like
- Swelling
- Pain or tenderness
- Nipple discharge from one or both breast

Goitre is an enlargement of thyroid gland due to iodine deficiency whereas tetany is a condition that is caused by the deficiency of calcium in blood.

Hence, the correct answer is option (B).

Note: From the above discussion it is clear that the abnormal condition in men where they develop enlarge mammary gland is due to unequal distribution of make and female hormones in men and hence due to excessive amount of female hormone they have large breasts size and this condition is called Gynaecomasita.
