Task: Answer the MCQ question.
Question: Which drug has a -1.677% 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: COc1cc(C(=O)ON=C2C(C)=CC(=O)C=C2C)cc(OC)c1OC
b: O=C(N/N=C/c1ccc(Cl)cc1)c1cc(-c2cccnc2)nc2ccccc12
c: C/C(=C/C=N/Nc1nc(N2CCCCC2)nc(N2CCCCC2)n1)c1ccccc1
d: Cc1ccc(NC(=O)CSc2nc3ccccc3c(=O)n2CCCC(=O)NCCCN2CCOCC2)cc1
e: O=C(OCc1cnc(Cl)s1)c1ccccc1Cl
Answer: b. O=C(N/N=C/c1ccc(Cl)cc1)c1cc(-c2cccnc2)nc2ccccc12
