Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.419\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCOCCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
b) COc1ccc(-n2nc(C(=O)NCC(=O)N3CCCCCC3)c3ccccc3c2=O)cc1
c) CCOC(=O)c1c(C)n(C)c2ccc(O)c(S(=O)(=O)c3ccccc3)c12
Answer: a. CCOCCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
