Task: Answer the multiple choice question.
Query: Which compound exhibits a -27.148\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1ncc(-c2ccc3c(c2)S(=O)(=O)c2cccc(C(=O)O)c2C3=O)cn1
b CCCCn1c(=O)c(C=Nc2cc([N+](=O)[O-])ccc2OC)c(O)n(CCCCl)c1=O
c Cc1ccc2c(c1)c(-c1csc(N)n1)c(C)n2C
Answer: b. CCCCn1c(=O)c(C=Nc2cc([N+](=O)[O-])ccc2OC)c(O)n(CCCCl)c1=O
