Problem statement: Answer the multiple choice question.
Query: Which drug has a -8.365\% 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 additional words.
Options:
a C/C(=N/NC(=O)CN1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1)c1ccco1
b CCC(=O)c1ccc(Oc2nc3c(c(=O)n(C)c(=O)n3C)n2CC)cc1
c COc1ccc(NC(=O)Cc2ccc(C)cc2)c([N+](=O)[O-])c1
d O=C(c1cnccn1)N1CCc2c([nH]c3ccccc23)C1c1cccc(Cl)c1
Answer: d. O=C(c1cnccn1)N1CCc2c([nH]c3ccccc23)C1c1cccc(Cl)c1
