Task: Answer the multiple-choice question.
Question: Which compound has a 8.865\% 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: O=C1c2ccccc2C(=O)N1Cc1cc(-c2ccccc2Cl)no1
b: CCOc1ccc(CCNC(=O)c2cccc3c2C(=O)N(CCOC)C3)cc1OCC
c: Nc1cc2c(cc1C(=O)c1ccccc1F)OCCO2
d: COc1ccc(C2CC(c3c(O)cc(C)oc3=O)=NCCS2)c(OC)c1
Answer: a. O=C1c2ccccc2C(=O)N1Cc1cc(-c2ccccc2Cl)no1
