Task: Answer the multiple choice question.
Question: Which compound has a 4.981\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(c1cccc(F)c1)N1CCN=C1SCc1cccnc1
[b] Cc1ccc(NC(=O)N2CCCC2C(=O)Nc2ccc(-n3cnnn3)c(C)c2)cc1
[c] CCCCOc1cccc(OCC(=O)Nc2nc3ccccc3[nH]2)c1
Answer: a. O=C(c1cccc(F)c1)N1CCN=C1SCc1cccnc1
