Task: Answer the multiple choice question.
Question: Which drug exhibits a 5.256\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCOC(=O)c1sc(NC(=O)CSc2nc(-c3ccco3)cc(C(F)(F)F)n2)c(C(=O)OC)c1C
b) COc1ccc(Cn2nnnc2C(c2cc3ccc(OC)cc3[nH]c2=O)N2CCC(C)CC2)cc1
c) O=C(CN1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)Nc1ccc(F)cc1F
d) O=C(NC1CCCCC1)C(c1ccc(O)cc1)N(C(=O)c1cnccn1)c1cccc(F)c1
Answer: d. O=C(NC1CCCCC1)C(c1ccc(O)cc1)N(C(=O)c1cnccn1)c1cccc(F)c1
