Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.761% 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(CSc1ccc([N+](=O)[O-])cn1)Nc1ccc2c(c1)OCCO2
b: O=C(c1cc2ccccc2o1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
c: O=C(NN1CCOCC1)c1cc(-c2cccs2)nc2ccccc12
d: COc1cccc(Cn2c(=O)oc3ccccc32)c1
Answer: a. O=C(CSc1ccc([N+](=O)[O-])cn1)Nc1ccc2c(c1)OCCO2
