The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept
The cerebral cortex is divided into four lobes by deep grooves called sulci.

Step 2: Boundaries
The central sulcus separates the frontal and parietal lobes. The parieto-occipital sulcus separates the parietal and occipital lobes.

Step 3: Temporal lobe
The temporal lobe is separated from the frontal and parietal lobes by the deep lateral groove called the sylvian sulcus. Succus entericus is intestinal juice and has nothing to do with the brain.

Final Answer:
The sylvian sulcus separates the temporal lobe from the frontal and parietal lobes. \[ \boxed{\text{(D) }\text{sylvian sulcus}} \]
