Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.697\% 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) COc1ccc(-n2c(SCC(=O)Nc3ccccc3)nnc2-c2ccc(NS(=O)(=O)c3ccc(C)cc3)cc2)cc1
(b) COC(=O)CSc1ncnc2c1cnn2-c1ccc(C)cc1C
(c) COc1cc(Nc2ccc(S(=O)(=O)N3CCN(C)CC3)cc2[N+](=O)[O-])cc(OC)c1
(d) O=C(OC(C(=O)Nc1ccc([N+](=O)[O-])cc1Br)c1ccccc1)c1ccccc1
Answer: b. COC(=O)CSc1ncnc2c1cnn2-c1ccc(C)cc1C
