Task: Answer the multiple-choice question.
Query: Which drug has a 0.142\% 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] N#CCCn1cc(C=C(C#N)C#N)c(-c2ccc(-c3ccccc3)cc2)n1
[b] O=C(O)c1ccc(-c2ncc[nH]2)cc1
[c] O=C(CSc1nc2nc(-c3cccs3)cc(C(F)(F)F)c2c(=O)[nH]1)Nc1ccc(F)c(F)c1
[d] O=C(NCCCn1ccnc1)NC(C(F)(F)F)C(F)(F)F
[e] CC(C)(CO)Nc1ncnc2onc(-c3ccc(F)cc3)c12
Answer: c. O=C(CSc1nc2nc(-c3cccs3)cc(C(F)(F)F)c2c(=O)[nH]1)Nc1ccc(F)c(F)c1
