Problem statement: Answer the multiple-choice question.
Question: Which compound has a 18.455\% 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.) c1ccc(C2(CN3CCNC[C@H]3Cc3cccc4ccccc34)CC2)cc1
b.) Cc1cc(C(=O)NCc2ccc(S(N)(=O)=O)cc2)c(C)o1
c.) O=C(Nc1cccc(-c2nc3ccccc3[nH]2)c1)c1ccco1
d.) O=C1CC(SC2=NCCS2)C(=O)N1c1ccc(Cl)cc1
Answer: c. O=C(Nc1cccc(-c2nc3ccccc3[nH]2)c1)c1ccco1
