D Correct answer
Explanation

Every human inherits approximately half of their DNA from their mother and half from their father. This equal contribution occurs because each parent contributes one set of chromosomes (23 in humans) to form the complete set of 46 chromosomes in the offspring. While siblings share some DNA, they are not the primary source of an individual's genetic material - that comes from the two biological parents.
