Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.630\% 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 additional words.
Options:
a: O=S(=O)(Nc1ccccc1Cl)c1ccc(F)cc1
b: CSc1ccc(/C=C(\NC(=O)c2ccccc2)C(=O)NCCN2CCOCC2)cc1
c: O=C(NCc1cccc(Br)c1)c1cc(-c2ccccc2)nn1CC1CC(c2cccnc2)=NO1
d: CCn1cc(C(=O)C(F)(F)F)c2ccccc21
Answer: a. O=S(=O)(Nc1ccccc1Cl)c1ccc(F)cc1
