Five children were adiminstered psychological tests to know their intellectual levels. In the report , psychologists pointed out that the child A is less intelligent than the child B. The child C is less intelligent than the child D. The child B is less intelligent than the child C and child A is more intelligent than the child E . Which child is the most intelligent ?

Options

A. A
B. B
C. D
D. E

Explanation

To solve the problem step by step, we will analyze the information given about the intelligence levels of the children.

### Step 1: Analyze the statements
1. **A is less intelligent than B**: This can be written as A < B.
2. **C is less intelligent than D**: This can be written as C < D.
3. **B is less intelligent than C**: This can be written as B < C.
4. **A is more intelligent than E**: This can be written as A > E, or E < A.

### Step 2: Combine the inequalities
From the statements, we can combine the inequalities:
- From A < B and B < C, we can conclude that A < B < C.
- From C < D, we can add this to the previous conclusion: A < B < C < D.
- From E < A, we can place E at the lowest level: E < A < B < C < D.

### Step 3: Determine the most intelligent child
Now, we have the complete order of intelligence:
- E < A < B < C < D

From this order, we can see that **D is the most intelligent child**.

### Final Answer
The most intelligent child is **Child D**.
