Task: Answer the multiple-choice question.
Query: Which drug has a 19.679\% 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] O=C(CSc1ccc2nnc(-c3ccccn3)n2n1)N1CCOCC1
[b] C/C=C(/C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@H](C(N)=O)N(C(=O)c2ccc(Cl)cc2)C3)c1
[c] O=C(O)Cc1sc(-c2ccccc2)nc1-c1ccccc1
[d] Cc1nn(C(C)C(=O)NCc2ccccc2F)c(=O)c2nn(-c3ccccc3)c(C)c12
[e] CCOC(=O)c1sc2ncnc(OC)c2c1C
Answer: d. Cc1nn(C(C)C(=O)NCc2ccccc2F)c(=O)c2nn(-c3ccccc3)c(C)c12
