Which is the first sign of puberty in girls?

• A. Pubic hair growth
• B. Thelarche
• C. Menarche
• D. Acne

Answer: (B)

The first sign of puberty in girls is thelarche, breast budding due to rising estrogen from ovarian maturation. This estrogen-driven change marks the onset of puberty and is usually the earliest visible sign. Pubic hair growth occurs later, driven by adrenal androgens (adrenarche). Menarche, the first menstrual period, typically follows several years after thelarche, after continued growth and breast development. Acne can appear during puberty but is not the initial sign.
