Task: Answer the multiple-choice question.
Query: Which drug has a 6.852\% 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, or c without using any other words.
Options:
a: O=C(Cn1nnc(-c2ccccc2)n1)OC1CCOC1=O
b: CCn1c(C(=O)Nc2ccsc2C(=O)OC)cc2sc(Cl)cc21
c: Cc1cccc(Nc2nc(NCc3ccco3)nc(N3CCOCC3)n2)c1
Answer: b. CCn1c(C(=O)Nc2ccsc2C(=O)OC)cc2sc(Cl)cc21
