Which of the following is a function of an organ in an organism?

The choice highlighting the execution of specialized functions accurately represents a key role of organs within an organism. Each organ is typically composed of various tissues that work together to perform specific tasks essential for the organism's survival and health. For example, the heart is specialized for pumping blood, while the lungs facilitate gas exchange. This specialization allows organs to carry out complex physiological processes efficiently, contributing to the overall functioning of the organism as a whole.

In contrast, while storing genetic information, producing energy, and transporting nutrients are important biological processes, these activities are typically associated with the functions of cells or cellular components rather than organs themselves. Genetic information is stored in the nuclei of cells, energy production primarily occurs in cellular organelles like mitochondria, and nutrient transport is often accomplished by blood vessels and cells rather than being a primary function of an organ directly. Therefore, the emphasis on executing specialized functions is a defining characteristic of organ roles within an organism.
