Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -9.138\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1nc(-c2ccc(Cl)cc2)nnc1C
b: COc1ccc(C(=O)NCC(=O)N/N=C/c2ccc([N+](=O)[O-])s2)cc1OC
c: CCn1ccnc1CN(C)Cc1cn(-c2ccc(C)cc2)nc1-c1cccc(C)c1
Answer: b. COc1ccc(C(=O)NCC(=O)N/N=C/c2ccc([N+](=O)[O-])s2)cc1OC
