Properties of organs are

The correct option is: a result of interaction among the constituent issues

Explanation:
Living organisms exhibit a hierarchical level of biological organization, starting from biomolecules, organelles, cells, tissues, organs, organ systems, and finally the complete organism.
At each successive level of this organizational hierarchy, new properties emerge that are not present at the lower level. These are known as emergent properties.

Specifically:
1. The properties of a tissue are not found in its constituent cells; instead, they arise due to the cooperative interactions among those cells.
2. Similarly, the properties of an organ are not present within its individual constituent tissues when isolated. Rather, the unique properties and functions of an organ emerge as a result of the complex interactions and coordination among the constituent tissues (referred to as "issues" in the option text) that make up the organ.

Therefore, the characteristics and functioning of organs are a result of interactions among their constituent tissues.
