Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.623\% 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 CC(/C=C1\SC(=O)N(CC(=O)Nc2cccc(O)c2)C1=O)=C\c1ccccc1
b CCOc1ccc(N)c(SSc2cc(OCC)ccc2N)c1
c COc1ccc(Cl)cc1N(CC(=O)N1CCCCC1)S(C)(=O)=O
d COc1ccc(CCNC(=O)C2CCCN(S(=O)(=O)c3cccc4nonc34)C2)cc1OC
Answer: b. CCOc1ccc(N)c(SSc2cc(OCC)ccc2N)c1
