Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.632\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCOc1ccccc1/C=C/c1cc(C(=O)O)c2ccccc2n1
[b] C(=C1\CCCC2=C1Nc1ncnn1C2c1ccccc1)\c1ccccc1
[c] Cc1coc2c1c(C)cc1oc(=O)c(CC(=O)NCCCCCC(=O)O)c(C)c12
Answer: b. C(=C1\CCCC2=C1Nc1ncnn1C2c1ccccc1)\c1ccccc1
