Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -1.879% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(N/N=C/c1ccc(Cl)c([N+](=O)[O-])c1)C1CC1
(b) Oc1ccccc1C(=S)N1CCN(c2cccc(Cl)c2)CC1
(c) Cc1ccc(S(=O)(=O)/N=C2\C(=O)c3ccccc3C([O-])=C2n2cc[n+](CCC(C)C)c2)cc1
(d) O=C1N/C(=C/c2cccn2-c2ccccc2)C(=O)N1c1cccc(Cl)c1
Answer: a. O=C(N/N=C/c1ccc(Cl)c([N+](=O)[O-])c1)C1CC1
