Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.052% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CN1CCN(c2ncccn2)CC1)c1ccc(F)cc1
b CCOC(=O)c1c(OCC)[nH]c2c1cc(O)c1ccccc12
c CCOC(=O)C(C)Oc1ccc(OCc2ccccc2)cc1
d COC(=O)C1=C(NC(=O)c2ccc(C)cc2)CCS1
Answer: c. CCOC(=O)C(C)Oc1ccc(OCc2ccccc2)cc1
