Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.784\% 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.) CCCN1CCC(NC(=O)Cc2ccc(C)cc2)CC1
b.) CCn1c(SCC(=O)N2CCc3ccccc3C2)nc2sc(C)c(C)c2c1=O
c.) O=C(O)c1ccc(-c2nc(-c3ccc(Cl)c(Cl)c3)cs2)cc1
Answer: b. CCn1c(SCC(=O)N2CCc3ccccc3C2)nc2sc(C)c(C)c2c1=O
