Task: Answer the multiple choice question.
Question: Which compound exhibits a 11.818\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(CCC(=O)c1ccc(Br)cc1)Nc1cccc(C(F)(F)F)c1
b: Cc1ccc2cc(C#N)c(N3CCCN(S(=O)(=O)c4ccc(F)cc4)CC3)nc2c1
c: CCC(Sc1ncnc2c1c(-c1ccccc1)cn2-c1ccc(OC)cc1)C(=O)OC
d: CCOCC(=O)Nc1cc(-c2cn3cccnc3n2)ccc1C
Answer: a. O=C(CCC(=O)c1ccc(Br)cc1)Nc1cccc(C(F)(F)F)c1
