This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Anaesthesia
True about xenon anaesthesia – a) Rapid induction and recoveryb) Low potencyc) High blood solubilityd) Non - explosivee) Heavier than air 
Select and explain. 
A. abcd, B. abde, C. acde, D. ade
B: abde
Answer: B: abde 
Explanation: Xenon is a heavy gas; it is 4.5 times heavier than air. It is non-inflammable and non-explosive.
Xenon is a weak anaesthetic with low potency.
Xenon has very low blood-gas partition coefficient, i.e. Very low blood solubility → induction & recovery are very fast.
