Task: Answer the multiple-choice question.
Query: Which compound has a -0.031\% 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 other words.
Options:
[a] Cc1cc(S(=O)(=O)N2CCN(c3ccccc3O)CC2)c(C)s1
[b] COc1cccc(N2CCN(C(=O)c3ccc(Cl)c(NC4=NC5CS(=O)(=O)CC5S4)c3)CC2)c1
[c] O=C1NC(=S)N/C1=C/c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])c(Cl)c1
[d] COc1ccccc1CNC(=O)C(NC(=O)C1CCCCC1)C(C)C
Answer: c. O=C1NC(=S)N/C1=C/c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])c(Cl)c1
