The weight of the child at 3 years is usually times the bih weight –

**Core Concept**
The question is testing the understanding of the concept of growth and development in children, specifically the relationship between birth weight and weight at 3 years of age. This concept is crucial in pediatrics as it helps in assessing the growth and nutritional status of children.

**Why the Correct Answer is Right**
The weight of a child at 3 years is usually 8-10 times the birth weight. This is because children grow and develop rapidly during the first few years of life, with the most significant growth occurring during the first year. The growth rate slows down after the first year, but children still grow and develop rapidly during the second and third years. The exact relationship between birth weight and weight at 3 years can vary depending on several factors, including genetics, nutrition, and overall health.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the weight of a child at 3 years is not typically 5-6 times the birth weight. This would be more characteristic of growth in the first year of life.
* **Option B:** This option is incorrect because the weight of a child at 3 years is not typically 12-15 times the birth weight. This would be more characteristic of growth in the first 2-3 years of life, but with an excessive rate of growth.
* **Option D:** This option is incorrect because the weight of a child at 3 years is not typically 4-5 times the birth weight. This would be more characteristic of growth in the first year of life, but with a slower rate of growth.

**Clinical Pearl / High-Yield Fact**
A good way to remember the relationship between birth weight and weight at 3 years is to use the "rule of 8s": a child's weight at 3 years is usually 8-10 times the birth weight. This rule can be useful in assessing the growth and nutritional status of children.

**Correct Answer:** C. 8-10 times.
