Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.471\% 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 additional words.
Options:
a) O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCc1ccc2c(c1)OCO2
b) O=C(Cc1ccccc1)n1nc(-c2ccco2)nc1SCc1ccccc1
c) COc1cccc(C2CC(c3ccccc3Cl)n3ncnc3N2)c1
d) Cc1cc(OCc2cc(C(=O)N(C)Cc3nonc3C)no2)cc(C)c1Cl
e) CC(=O)c1cc(C(C)=O)c(C)[n+](C)c1C.[O-][Cl+3]([O-])([O-])[O-]
Answer: a. O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCc1ccc2c(c1)OCO2
