Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -74.194\% 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, or d without using any other words.
Options:
a) COc1ccc(N=C2S/C(=C\c3cc(C)n(C)c3C)C(=O)N2CC(C)C)cc1
b) O=C(CCNC(=O)c1ccccc1)N/N=C/c1ccc([N+](=O)[O-])cc1
c) OC(CNCC1(N2CCCCC2)CCCCC1)COc1ccc(Cl)cc1Cl
d) COc1cc(OC)cc(C(=O)O/N=C(\N)c2ccccn2)c1
Answer: c. OC(CNCC1(N2CCCCC2)CCCCC1)COc1ccc(Cl)cc1Cl
