**Core Concept**
The question tests understanding of **mandibular movement** and **occlusal contacts** in the context of **temporomandibular joint (TMJ) function** and **dental occlusion**. It requires knowledge of how the mandible moves from the **retruded contact position (RCP)** to the **intercuspal position (ICP)**.

**Why the Correct Answer is Right**
The movement from RCP to ICP can involve **lateral**, **anterior**, and **posterior** components as the mandible moves to achieve the most stable occlusal position. However, the specific exception depends on understanding the typical paths of mandibular movement and the definitions of these positions.

**Why Each Wrong Option is Incorrect**
**Option A:** May be involved in certain movements but is not the exception when considering typical movements from RCP to ICP.
**Option B:** Can occur as part of the movement to achieve ICP from RCP, especially if there's a lateral component to the slide.
**Option C:** Might seem plausible but isn't the correct exception given the context of the question.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the **retruded contact position** is often considered the most posterior position of the mandible where the condyles are in their most superior and posterior positions in the glenoid fossae, and from this position, the mandible typically moves **anteriorly** and possibly **laterally** to reach the **intercuspal position**.

**Correct Answer:** D. No movement
