**Core Concept**
The patellar plexus is a complex network of nerves that provides sensation to the anterior aspect of the knee, specifically the skin overlying the patella. This plexus is formed by the terminal branches of the femoral nerve, which is a major nerve of the lower limb.

**Why the Correct Answer is Right**
The patellar plexus is indeed formed by the contributions of three cutaneous nerves: the medial, intermediate, and lateral cutaneous nerves of the thigh. These nerves arise from the femoral nerve, which is a mixed nerve that provides both motor and sensory innervation to the lower limb. The medial cutaneous nerve of the thigh provides sensation to the medial aspect of the knee, while the intermediate cutaneous nerve provides sensation to the middle aspect. The lateral cutaneous nerve of the thigh provides sensation to the lateral aspect of the knee. The convergence of these nerves at the patella forms the patellar plexus.

**Why Each Wrong Option is Incorrect**
**Option A:** The lateral cutaneous nerve of the thigh does contribute to the patellar plexus, but it is not the only nerve involved. Therefore, this option is incorrect.
**Option B:** The intermediate cutaneous nerve of the thigh is also a contributor to the patellar plexus, but like option A, it is not the sole nerve involved. This option is incorrect.
**Option C:** The medial cutaneous nerve of the thigh contributes to the patellar plexus, but again, it is not the only nerve involved. This option is incorrect.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the patellar plexus is a complex network of nerves, and any damage or injury to this area can result in sensory deficits or pain. A thorough understanding of the anatomy of the lower limb, including the nerves that contribute to the patellar plexus, is crucial for diagnosing and managing conditions affecting this region.

**✓ Correct Answer: D. All of the above**
