Answer: (A)

Puberty tends to unfold in a fairly consistent sequence: the first sign is activation of the gonads leading to visible secondary sexual characteristics (breast development in girls or testicular enlargement in boys). This is followed by pubic hair development, then a rapid growth spurt driven by rising sex steroids and growth hormone, and finally the attainment of reproductive capability (menarche in girls, spermarche in boys). The option that lists these events in that earliest-to-latest order matches how puberty typically progresses. In boys, the same general pattern holds: testicular enlargement first, then pubic hair, then the growth spurt, and finally spermarche. Other sequences would place later events (like menarche) before the initial gonadal changes or reorder the growth spurt, which doesn’t fit the usual maturation timeline.
