Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.016\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1cccc(NC(=O)CSc2nc3ccccc3n2C)c1
b: O=C(N/N=C/C=C/c1ccccc1)c1ccccn1
c: Cc1ccc(C(=O)C2=C(O)C(=O)N(Cc3cccnc3)C2c2ccc(OC(C)C)cc2)o1
d: Oc1ccc(Cl)cc1C=Nc1ccccc1Br
Answer: b. O=C(N/N=C/C=C/c1ccccc1)c1ccccn1
