Task: Answer the multiple choice question.
Question: Which drug has a 1.560\% 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. CCOc1ccc(-n2nnnc2SCC(=O)Nc2ccc(NC(C)=O)cc2)cc1
b. COC(=O)/C=C1/N/C(=N\c2nc(C)cc(C)n2)N(c2cccc(C)c2)C1=O
c. O=C(Nc1ccccc1Br)C1CC(=O)N(c2ccc3c4c(cccc24)CC3)C1
d. N#C/C(=C\c1cccc(Cl)c1)C(=O)c1ccccc1
e. CC(N=Cc1nc(-c2ccccc2)oc1O)c1ccccc1
Answer: b. COC(=O)/C=C1/N/C(=N\c2nc(C)cc(C)n2)N(c2cccc(C)c2)C1=O
