Task: Answer the multiple choice question.
Question: Which compound has a 7.061\% 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. Cc1cc(NC(=O)CCCC(=O)NCc2cccs2)no1
b. O=c1cc(-c2ccccc2)c2ccc(O)c(CN3CCCCC3)c2o1
c. Cn1cccc1/C=C1/SC(=O)N(CC(=O)N2CCCC2)C1=O
d. Cc1ccc(S(=O)(=O)NC2=NCN(CCOC(=O)c3ccc([N+](=O)[O-])cc3)CN2)cc1
Answer: b. O=c1cc(-c2ccccc2)c2ccc(O)c(CN3CCCCC3)c2o1
