Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.768\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=S(=O)(NCCc1ccccn1)c1ccc(OC(F)(F)F)cc1
(b) O=C(NCC1(N2CCCCC2)CCCCC1)c1cccc([N+](=O)[O-])c1
(c) CSc1ccc(C(=O)C2CCCN(C(=O)c3ccc4c(c3)no[n+]4[O-])C2)cc1
(d) COc1ccnc2c1c(=O)n(Cc1ccc(F)cc1)c(=O)n2C
(e) COc1ccc(Cc2nc3ccccc3n2C)cc1.Cl
Answer: b. O=C(NCC1(N2CCCCC2)CCCCC1)c1cccc([N+](=O)[O-])c1
