Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.793\% 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: Cc1c(NC(=O)Nc2ccc(F)cc2F)c(=O)n(-c2ccccc2)n1C
b: CCOC(=O)Nc1ccc(=O)n(Cc2c(Cl)cccc2Cl)c1
c: COc1ccc(S(=O)(=O)n2ccc(C(C)Oc3ccc(-c4ccccc4)c(F)c3)n2)cc1
d: CC(C)[NH+]1CCC2(CC1)C(C#N)=C(N)NC([S-])=C2C#N
e: CCOc1ccc(CCNC(=O)Nc2ccccc2C)cc1OCC
Answer: a. Cc1c(NC(=O)Nc2ccc(F)cc2F)c(=O)n(-c2ccccc2)n1C
