According to Wechsler intelligence scale scoring,average IQ of a normal child is:

**Core Concept**
The Wechsler Intelligence Scale for Children (WISC) is a standardized test used to assess the cognitive abilities of children between the ages of 6 and 16. The test yields a full-scale IQ score, which is a composite measure of verbal comprehension, visual-spatial skills, and working memory.

**Why the Correct Answer is Right**
The average IQ score on the WISC is considered to be a standard reference point, with an average score of 100 representing a typical or average performance. This score is based on a large sample of children who have taken the test, and it is used as a baseline for comparison purposes. The WISC is normed to have a mean of 100 and a standard deviation of 15, which means that the majority of children will score between 85 and 115.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because there is no widely accepted average IQ score for children that is significantly higher than 100.
* **Option B:** This option is incorrect because the average IQ score for children is not typically considered to be around 50.
* **Option C:** This option is incorrect because there is no widely accepted average IQ score for children that is significantly lower than 50.

**Clinical Pearl / High-Yield Fact**
It's worth noting that IQ scores are not necessarily a perfect measure of intelligence, and there are many criticisms of the concept of IQ as a single, unitary construct. However, the WISC and other standardized intelligence tests can still be useful tools for identifying children who may be at risk for learning difficulties or other cognitive problems.

**Correct Answer: C. 100**
