Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.489\% 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 CCN1C(=O)CC(NCc2ccc(S(N)(=O)=O)cc2)C1=O
b Cc1ccc(-n2ncc3c(=O)n(CC#N)cnc32)cc1C
c CC(C)Cn1c(-c2cc(Br)ccc2F)nc2c1c(=O)[nH]c(=O)n2CC(C)C
d CCC(=O)Oc1ccc2ccccc2c1CNC(=O)c1ccccc1
Answer: c. CC(C)Cn1c(-c2cc(Br)ccc2F)nc2c1c(=O)[nH]c(=O)n2CC(C)C
