The growth of girls is more rapid than boys in

Question

Accepted Answer

The correct option is (2):
The growth of girls is more rapid than boys primarily during the adolescent growth spurt, which typically occurs earlier for females. This pubertal growth spurt in girls often begins around 10 to 11 years of age, reaching its peak velocity (the period of fastest growth) around 11 to 12 years. This period of rapid acceleration in height and weight occurs well within the general age span of 13 to 19 years, representing the earlier onset of puberty and physical maturation in girls compared to boys. While boys eventually achieve a higher peak growth velocity and continue growing for a couple of years longer, the initial period where girls' growth rate outstrips that of boys happens early in the adolescent stage.

The incorrect option is (1):
The age range of 6 to 10 years corresponds to middle childhood, which is generally characterized by a slow and steady rate of growth, rather than a "rapid" one. The dramatic increase in growth rate known as the adolescent growth spurt usually begins at the very end of this period or immediately afterward, around the age of 10 or 11 for girls. Therefore, this period does not accurately represent the stage when girls' growth is most rapid.

The incorrect option is (3):
The age range of 19 to 25 years represents the transition into early adulthood. By the age of 19, linear growth (increase in height) is almost entirely complete for both females and males, as the growth plates in the bones have fused. Consequently, there is no longer a "rapid growth" phase for either gender during this age period.

The incorrect option is (4):
The age range of above 25 years is classified as full adulthood. Skeletal maturation and the cessation of the growth spurt occur much earlier in life, typically in the mid to late teens. By age 25, the body is fully mature and no further increases in height are expected, making it impossible for girls to experience a growth rate more rapid than boys' during this time.
