Task: Answer the multiple choice question.
Query: Which drug exhibits a -8.424\% 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 O=S(=O)(Nc1nnc(C2CCCCC2)s1)c1ccc(F)cc1
b O=C(/C=C/c1ccco1)Nc1cccc2cccnc12
c COc1ccccc1CN1C[C@@H]2C[C@@H](c3ccccc3)N3CCC[C@@]23C1=O
d CCOC(=O)c1ccc(NC(=O)CSC(=S)N2CCOCC2)cc1
Answer: a. O=S(=O)(Nc1nnc(C2CCCCC2)s1)c1ccc(F)cc1
