The exocrine glands make chemicals that perform specific jobs in the area where they are released. Major exocrine products include the digestive juices, mucus, sweat and which?

Explanation:
Tears are the exocrine product that fits here. Exocrine glands release substances through ducts onto surfaces; tears come from lacrimal glands and are released onto the surface of the eye. This mirrors digestive juices being released into the digestive tract and sweat onto the skin, and mucus onto mucous membranes. The other options aren’t exocrine products: hormones and insulin are endocrine, meaning they’re released into the bloodstream; urine is produced by the kidneys, not secreted by exocrine glands onto a surface.
