In the classification of matter, all organic molecules contain which element?
A
Carbon (C)
B
Nitrogen (N)

Sulfur (S)
D
Oxygen (O)
Verified step by step guidance1
Understand that organic molecules are primarily defined by the presence of a specific element that forms the backbone of these compounds.
Recall that organic chemistry is the study of carbon-containing compounds, which means carbon is the central element in all organic molecules.
Recognize that while elements like nitrogen (N), sulfur (S), and oxygen (O) can be present in organic molecules, they are not required in every organic molecule.
Therefore, identify carbon (C) as the essential element that must be present in all organic molecules.
Conclude that the correct answer is carbon (C) because it is the fundamental element in the classification of organic matter.
