Question

all organisms contain and require it to survive. helium carbon zinc polonium

Explanation:

To determine the correct answer, we analyze the role of each element in organisms. Helium is a noble gas with no biological role. Zinc is an essential trace element but not universal to all organisms in the same fundamental way. Polonium is a radioactive element and not required for survival. Carbon, however, is a key element in all organic molecules (like carbohydrates, proteins, lipids, nucleic acids) and is essential for the structure and function of all living organisms.

Answer:

carbon (the option with "carbon" text, as it is the element all organisms contain and require for survival)
