Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.467\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) COc1ccc(Cl)cc1/C=C1/C(=O)ON=C1C
b) O=C(Nc1ccccc1Oc1ccccc1)c1cc([N+](=O)[O-])ccc1Cl
c) CC(C)(C)C1C/C(=C/c2ccccn2)C(=O)/C(=C/c2ccccn2)C1
d) O=c1nc2ccccc2c(NS(=O)(=O)c2ccccc2)n1-c1ccccc1
e) CC(CNC(=O)CN1C(=O)COc2ccc(S(=O)(=O)N3CCCCC3)cc21)c1ccccc1
Answer: a. COc1ccc(Cl)cc1/C=C1/C(=O)ON=C1C
