The correct Answer is:
D
The TCA cycle starts with the condensation of acetyl group with oxaloacetic acid and water to yield citric acid. It is tricarboxylic 6-carbon compound and undergoes reorganisation in the presence of iron containing enzyme aconitase first forming cis aconitrate and releasing water
