Task: Answer the multiple-choice question.
Question: Which compound has a -54.757\% 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: Cl.O=C(NCCCN1CCOCC1)c1coc2ccccc2c1=O
b: C=CCn1c(COc2ccc(F)cc2)nnc1SCC(=O)NC1CCS(=O)(=O)C1
c: O=C(CN1CCN(C(=O)c2ccccc2)CC1)Nc1ccc(Cl)cc1F
d: COc1ccc(-c2nn(-c3ccccc3)cc2CNC(C)Cn2cncn2)c(F)c1
Answer: c. O=C(CN1CCN(C(=O)c2ccccc2)CC1)Nc1ccc(Cl)cc1F
