Which is the first pubertal change in girls?

Explanation:
Thelarche is the first pubertal change in girls. It refers to the development of breast buds triggered by rising estrogen, signaling the onset of puberty. This breast development typically appears first, around ages 8 to 13, before other secondary sexual characteristics. After thelarche, pubarche (growth of pubic hair) appears due to adrenal androgens, followed by a growth spurt driven by estrogen and growth hormone, and finally menarche, the first menstrual period, usually after the peak growth. So, breast development marks the initial step in the sequence of pubertal changes.
