Task: Answer the multiple-choice question.
Question: Which compound has a 2.754\% 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 other words.
Options:
[a] CCOC(=O)Cc1csc(NC(=O)CCCC(=O)O)n1
[b] Cc1cc2c(cc1S(=O)(=O)N(C)Cc1ccccc1)OCC(=O)N2
[c] O=Cc1cccc(OCc2cccc3ccccc23)c1
[d] O=C(Cc1ccccc1F)NCC1(N2CCOCC2)CCCCC1
Answer: d. O=C(Cc1ccccc1F)NCC1(N2CCOCC2)CCCCC1
