Which of the following terms is associated with "nucle/o"?

The term "nucle/o" is a combining form used in medical terminology that specifically relates to the nucleus. The nucleus is the central and most important part of a cell, containing the genetic material, DNA, which dictates cellular function and hereditary information. The combining form "nucle/o" derives from the Latin word "nucleus," meaning "kernel" or "core," emphasizing its role as the control center and vital component of cellular structure.

In contrast, the other options do not relate to "nucle/o." While "cell" is a basic unit of structure and function in living organisms, "cell" is represented by the combining form "cellul/o" or simply "cell." The term associated with "eye" is "ocul/o" or "ophthalm/o," and "night" does not pertain to this context, as it is typically represented by "nyct/o." Therefore, "nucle/o" clearly correlates to the nucleus, affirming option B as the correct association.
