Final answer:
The average height of a 2-year-old is between 32 to 35 inches, aligning with the WHO growth standards for children.
Step-by-step explanation:
The average infant height at 2 years of age is typically between 32 to 35 inches. This information corresponds with growth standards from the WHO Multicentre Growth Reference Study Group, which indicate that a child's average length at birth is 19.5 inches, increasing to about 29.5 inches by 12 months and reaching an average of 34.4 inches by the age of 2 years. Given that the growth in height and weight is quite rapid in the first years of life, and considering the weight and height growth of toddlers, the correct answer to the question would be A.) 32 to 35 inches.
