Task: Answer the multiple choice question.
Query: Which drug has a 2.631\% 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 other words.
Options:
(a) CCOc1ccc(-n2c(=O)c3sccc3n(CC(=O)NCC3CCCO3)c2=O)cc1
(b) COc1cc(-c2nnc(COC(=O)c3cc(C)no3)o2)cc(OC)c1OC
(c) O=C(Oc1ccccc1F)c1ccc2c(=O)n3c(nc2c1)CCC3
(d) COc1ccc(NC(=O)CSc2nc(N)c(-c3ccccc3)c(=O)[nH]2)cc1
(e) O=C(NN=C1CCCCC1)c1cc(-c2ccccc2)n[nH]1
Answer: b. COc1cc(-c2nnc(COC(=O)c3cc(C)no3)o2)cc(OC)c1OC
