Final answer:

Tears from the lacrimal lake drain through the nasolacrimal duct to open into the nasal cavity, which can cause a runny nose when crying.

Step-by-step explanation:

The correct answer to the question "Where do tears go from the lacrimal lake?" is a) Nasolacrimal duct. The lacrimal apparatus functions to maintain the moist surface of the eye, and its drainage system includes a nasolacrimal canal that extends inferiorly from the lacrimal fossa, which is a depression in the lacrimal bone. Tears drain from the eye through this canal to open into the nasal cavity behind the inferior nasal conchae. This is what typically causes a runny nose when crying or experiencing eye irritation, due to the anterior flow of an increased amount of tears.
