Task: Answer the multiple-choice question.
Query: Which compound has a 2.779\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C1CC(c2ccccc2)=NN1c1nc(-c2ccccc2)cs1
b: CCOC(=O)N1CCN(c2nc3ccc(C(=O)c4ccccc4)cc3n3cnnc23)CC1
c: O=C(Nc1nc2ccccc2s1)C1c2ccccc2Oc2ccccc21
d: O=C(O/N=C1/CCCc2occc21)c1ccc(F)cc1
e: Cc1onc(-c2c(Cl)cccc2Cl)c1C(O)c1ccccc1
Answer: c. O=C(Nc1nc2ccccc2s1)C1c2ccccc2Oc2ccccc21
