    The six most important chemical elements of life are c. Carbon, nitrogen, oxygen, hydrogen, phosphate, and sulfur

    Explanation:

    Oxygen is the most abundant element and carbon is part of living organisms. Nitrogen is also abundant and hydrogen is a simple element that is found in all living organisms as well. Therefore, all of these 4 should be present in the answer. This excludes answers: a, b and d. The differences between c and e is that c includes sulfur while e includes calcium. Both include phosphate which is part of DNA and RNA. This leaves to decide which one is found in the highest concentration. Calcium is part of bones and compositions of several living organisms but sulfur is found in essential amino acids and it is necessary for bacteria and other microorganisms. So, c would be the correct answer.
