Task: Answer the multiple-choice question.
Query: Which drug has a 20.000\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1ccc(CCNC(=O)COC(=O)Cn2cnc3ccccc32)cc1OC
b.) O=C(Nc1ccccc1)C1=C(O)CC(c2ccoc2)CC1=Nc1ccccc1
c.) O=C(c1cccs1)N(c1ccc(F)cc1)C1C=CS(=O)(=O)C1
d.) COc1ccc(/C=N/Nc2nc(=O)[nH]nc2C)cc1OC
Answer: a. COc1ccc(CCNC(=O)COC(=O)Cn2cnc3ccccc32)cc1OC
