Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.962\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) Nn1c(SCC(=O)Nc2ccc(S(N)(=O)=O)cc2)nnc1C(F)(F)F
b.) CC(NC1CCN(Cc2ccccc2)CC1)c1ccc(F)cc1
c.) Cn1c(NCCCN2CCOCC2)nc2c1c(=O)n(Cc1ccc(Cl)cc1)c(=O)n2C
d.) O=c1n(Cc2ccccc2F)c2ccccc2n1Cc1ccccc1F
Answer: c. Cn1c(NCCCN2CCOCC2)nc2c1c(=O)n(Cc1ccc(Cl)cc1)c(=O)n2C
