Task: Answer the multiple choice question.
Query: Which compound has a 11.264\% 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) C=CCOc1c(Cl)cc(CNc2ccc3[nH]c(=O)[nH]c3c2)cc1OC
(b) COc1cccc(/C=C/C(=O)Nc2ccc3c(c2)OCCO3)c1
(c) Cc1ccn2cc(-c3cccc(S(=O)(=O)N4CC(C)OC(C)C4)c3)nc2c1
Answer: a. C=CCOc1c(Cl)cc(CNc2ccc3[nH]c(=O)[nH]c3c2)cc1OC
