Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.489% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CC(CCO)Nc1nc2c([nH]1)c(=O)n(C)c(=O)n2C
b. O=S(=O)(Nc1nc2ccccc2nc1Nc1ccc(N2CCOCC2)cc1)c1cc(Cl)ccc1Cl
c. Cc1c(C(=O)Nc2ccccn2)oc2ccccc12
Answer: a. CC(CCO)Nc1nc2c([nH]1)c(=O)n(C)c(=O)n2C
