Task: Answer the multiple-choice question.
Query: Which drug has a -0.090\% 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(COc1ccccc1Cl)Nc1nc(-c2cccs2)cs1
b Cc1nn(Cc2ccc(Cl)cc2)c(C)c1NC(=O)Cn1nc([N+](=O)[O-])c(Cl)c1C
c CCCCNC(=O)Nc1cc(C(=O)OC)ccc1C
d Cc1cccc(NC(=O)CSc2nnc(-c3ccc(S(=O)(=O)N4CCCC4)cc3)o2)c1
e COCN1C=Nc2cccc3cccc1c23
Answer: a. O=C(COc1ccccc1Cl)Nc1nc(-c2cccs2)cs1
