Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.990\% 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: CCOc1ccc(CCNC(=O)c2ccc(S(=O)(=O)N3CCCC3)cc2)cc1OCC
b: O=C(NC1CCCCC1)c1cccc(COCC(F)(F)F)c1
c: COc1cc(/C=N/NC(=O)C(C)n2nnc3ccccc32)ccc1O
d: Cc1cc(N2CCN(C(=O)c3cccs3)CC2)c(F)cc1[N+](=O)[O-]
Answer: b. O=C(NC1CCCCC1)c1cccc(COCC(F)(F)F)c1
