Explanation / Answer
We can answer only one question per post.
The answer to 9th question is
B)
atropine and acetylcholinesterase.
----------------------------------
Atropine acts on acetylcholine receptors while acetylcholinesterase degrades acetyl choline.
Hence, the new compound which is antagonistic to the acetyl choline receptors and also degrades acetyl choline contains the properties of both acetyl cholinesterase and atropine.
