no pyruvate carboxylase ....no gluconeogenesis...pyruvate has to be converted to alanine n lactate

I chose D as well. However, Kaplan chooses E. Explanation is that the symptoms are not consistent with PCD.
I did some research online and found out that both diseases have similar clinical symptoms. My conclusion is that this Q is not well written.
Answers for you guys confirm my hypothesis. thanks
