Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.651\% 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 COc1ccc(CN2CSC(=S)N(Cc3ccc(OC)cc3)C2)cc1
b O=c1[nH]c2nc(SCc3ccc(Cl)cc3)ncc2c(=O)n1-c1ccccc1
c COc1cc(SC)ccc1C(=O)Nc1ccccn1
Answer: b. O=c1[nH]c2nc(SCc3ccc(Cl)cc3)ncc2c(=O)n1-c1ccccc1
