Problem statement: Answer the multiple-choice question.
Query: Which drug has a 10.797\% 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] COc1ccc(/C=N/NC(=O)c2ccccc2O)cc1Cn1nnc2ccccc21
[b] O=C1NC(=O)C(c2ccccc2)(c2ccc(O)cc2)N1
[c] CCOC(=O)N1CCN(C(=O)c2ccc3c(c2)N(Cc2ccc(F)cc2)CCS3)CC1
[d] O=C(Cn1cc(C(F)(F)F)cc(Cl)c1=O)Nc1ccc(N2CCOCC2)cc1
Answer: b. O=C1NC(=O)C(c2ccccc2)(c2ccc(O)cc2)N1
