**Core Concept**
The appendix is a small, tube-like structure attached to the large intestine, and its development, anatomy, and blood supply are crucial aspects of understanding its function and clinical significance. The **appendix** develops from the **midgut**, which is one of the three primary divisions of the embryonic gut. The blood supply to the appendix is also an important consideration in surgical procedures.

**Why the Correct Answer is Right**
The correct answer, **c) Develops from midgut**, is accurate because the appendix indeed develops from the midgut portion of the embryonic gut. This is supported by embryological studies that show the appendix forms as a diverticulum from the midgut. The **midgut** gives rise to the distal portion of the duodenum, jejunum, ileum, and the proximal two-thirds of the transverse colon, including the appendix.

**Why Each Wrong Option is Incorrect**
**Option A:** The appendix does have a **mesentery**, known as the mesoappendix, which attaches it to the ileum.
**Option B:** The taenia coli are longitudinal bands of smooth muscle found on the colon, not the appendix.
**Option D:** The appendix is supplied by the **appendicular branch of the ileocolic artery**, but stating it as "supplied by appendicular branch of ileocolic" might be misleading without specifying the artery.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the appendix develops from the **midgut**, which has implications for its blood supply and innervation. This is important in understanding the clinical presentation and management of appendicitis.

**Correct Answer:** D. c) Develops from midgut
