Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.641\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCCCCCn1c(=O)[nH]c2c(c1=O)CCC2
b) CO/N=C/C(c1ccc(Cl)nc1)S(=O)(=O)c1ccccc1
c) O=S(=O)(Nc1ccc(-n2cccc2)cc1)c1ccccc1
Answer: a. CCCCCCn1c(=O)[nH]c2c(c1=O)CCC2
