**Core Concept**
Brodmann areas are a system of parcellation of the cerebral cortex developed by Korbinian Brodmann, which divides the cortex into areas based on their cytoarchitectural characteristics. These areas are involved in various higher brain functions, including sensory perception, motor control, and cognition.

**Why the Correct Answer is Right**
The primary somatosensory cortex, responsible for processing tactile and proprioceptive information, is located in Brodmann area 1, 2, and 3. These areas receive input from the thalamus and are crucial for processing sensory information from the body. The somatosensory cortex is organized in a somatotopic manner, meaning that different parts of the body are represented in different areas of the cortex. This organization allows for precise localization of sensory information.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify the correct Brodmann area for the somatosensory cortex. While Brodmann area 4 is involved in motor control, it is not responsible for somatosensory processing.
* **Option B:** This option is incorrect because it does not accurately represent the somatosensory cortex. Brodmann area 5 is involved in the processing of sensory information from the body, but it is not as specifically localized to the primary somatosensory cortex as areas 1, 2, and 3.
* **Option C:** This option is incorrect because it does not correctly identify the Brodmann area for the somatosensory cortex. While the lateral occipital complex is involved in object recognition, it is not responsible for processing somatosensory information.

**Clinical Pearl / High-Yield Fact**
The somatosensory cortex is organized in a somatotopic manner, with different parts of the body represented in different areas of the cortex. This organization is crucial for precise localization of sensory information and is often disrupted in neurological disorders such as stroke or traumatic brain injury.

**Correct Answer: D. 1, 2, and 3**
