A Correct answer
Explanation

Nematoblasts (also called cnidoblasts) are specialized cells in Cnidaria that develop into stinging cells (cnidocytes). They are derived from interstitial cells (I-cells), which are multipotent stem cells in cnidarians. Gland cells, mesoepithelial cells, and nerve cells do not give rise to nematoblasts.
