Which term describes the first physical sign of puberty in girls?

Explanation:
The earliest outward sign of puberty in girls is thelarche—the development of breast buds due to rising estrogen from the ovaries, signaling the start of gonadal maturation. Adrenarche involves adrenal hormones leading to pubic hair and body odor and can occur around the same time but is not the first visible sign of puberty. Menarche is the first menstrual period and happens after thelarche, typically about a year later. Gynecomastia refers to male breast tissue development and isn’t relevant to girls.
