Task: Answer the multiple-choice question.
Question: Which drug has a 3.117\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) N#CCCn1cc(C(=O)N2CCCCC2)c(-c2cccc([N+](=O)[O-])c2)n1
b) CCN(Cc1ccncc1)C(=O)CSc1ccc2ccccc2c1
c) CCCc1cc(=O)oc2cc(OCc3cccc(OC)c3)c(Cl)cc12
d) O=C(O/N=C1/CCCc2occc21)c1ccc(Cl)cc1Cl
e) O=C1N/C(=N\S(=O)(=O)Cc2ccccc2)S/C1=C/c1cccc([N+](=O)[O-])c1
Answer: b. CCN(Cc1ccncc1)C(=O)CSc1ccc2ccccc2c1
