Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.814\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCCCC1=CC2=C(c3ccco3)C(=O)C(C)(OC(=O)c3ccc(OC)cc3)C(=O)C2=CN1CCCN(CC)CC
b. O=C(Nc1nnc(C2CCCCC2)s1)c1cccs1
c. CC(=O)c1cnc2nc(SCc3cccc(C)c3)nn2c1C
d. COc1ccc(C)cc1NC(=O)Nc1cccc(C)c1
Answer: b. O=C(Nc1nnc(C2CCCCC2)s1)c1cccs1
