Step-by-step explanation:
A ketogenic amino acid can be defined as the amino acid which can be broken down directly into Acetyl co-A. This is the precursor molecule of ketone bodies and myelin during the early development in humans. lysine and leucine are examples of ketogenic amino acids
These amino acids cannot be form glucose since both of the carbon atoms of c body get degraded during citric acid cycle to carbon dioxide.
Thus, the correct answer is Option B
