Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.648\% 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: COc1ccc(CN(C)CC(=O)NC(=O)NCc2ccccc2)c(OC)c1
b: O=C(NNC(=O)c1cccs1)c1csc(N2CCOCC2)n1
c: CCC(=O)N/C(N)=N/c1nc2ccccc2o1
d: CCOc1ccc(CNC(=O)C(=O)c2cn(CC(=O)N3CCOCC3)c3ccccc23)cc1OC
Answer: b. O=C(NNC(=O)c1cccs1)c1csc(N2CCOCC2)n1
