Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -63.218% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1c(OC2OC(C(=O)O)C(O)C(O)C2O)cc(O)c2c(=O)cc(-c3ccccc3)oc12
b: O=c1c2[nH]c3ccc(F)cc3c2ncn1CCN1CCN(Cc2ccccc2)CC1
c: O=C(CCn1nc(-c2ccccc2)c2ccccc2c1=O)NCC1CCCO1
d: COc1ccc(-n2nc(C(=O)NCc3ccco3)c3c4ccccc4n(C)c3c2=O)cc1Cl
e: NN/C(=C\[N+](=O)[O-])Nc1ccc(Cl)cc1
Answer: b. O=c1c2[nH]c3ccc(F)cc3c2ncn1CCN1CCN(Cc2ccccc2)CC1
