A.) Change the landscape through erosion
The correct answer is "A. carbon, hydrogen, oxygen and nitrogen".
Scientists believe that out of the 116 known elements, only 25 are used
by mammals (and therefore by humans). Out of the 25 elements that are
believed by scientists to support human life, only four of these
elements - carbon, oxygen, hydrogen, and nitrogen - make up about 96% of
the human body and are found in the basic structure of all biochemical
molecules within the human body. Because of this, carbon, hydrogen,
oxygen, and nitrogen are considered "the four essential elements"
supporting human life. However, it is also important to keep in mind
that although many of the other 25 elements present in the human body
are required in only small amounts, they play an important role in
keeping the body functioning correctly, as well.

Explanation:
A sex-linked trait is a trait which is inherited on the sex chromosomes (X and Y chromosomes). This means that that trait is only inherited by offsprings of a particular sex. In this question, a family is said to have a Y-linked disease that affects the father.
Note that, Y chromosomes are only present in the male sex, meaning that a father will always transfer its Y chromosome to all his male offsprings. Since this disease (trait) is on the Y chromosome, it means that all male offsprings i.e. 100% of this father will have the disease.
