Correct Answer: Option D
In a row of 10 children, A is the 3rd child from the left end, and B is the 6th child from the right end. We need to find the total number of children between A and B.
The distance between A and B will include all the children between them, excluding A and B themselves. To calculate this, we need to subtract 1 from the sum of the positions of A and B.
Position of A = 3
Position of B = 10 - 6 + 1 = 5
Total number of children between A and B = Position of B - Position of A - 1
= 5 - 3 - 1
= 1
Therefore, there is 1 child between A and B.
The correct answer is D) 1 child.
