d. The epidermis is associated with sensing the environment and prey capture.

Explanation:

Most cnidarians have two layers of cells organized into some luck of tissues that have specific functions.

Cnidarians' body organization is simple: It is a hollow structure composed of two cellular layers: epidermis, which is the external layer, and gastrodermis that is the internal layer, formed by lining cells in the gastrovascular cavity. Between these two layers, place the mesoglea that varies from a thin non-cellular membrane to a mucous, fibrous, thick membrane with amebocytes.      

Epidermis and gastrodermis originate from two embryonic tissues, the ectoderm, and the endoderm, respectively.

The epidermis has five types of cells with different functions: epitheliomuscular, interstitial, cnidoblasts, secretors, and sensorial.

Gastrodermis is composed of cells such as nutritive cells, glandular enzymatic cells, secretory cells, and sensory cells.  

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
