Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.675\% 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, c, d, or e without using any additional words.
Options:
a.) O=C1CCC([N+](=O)[O-])C(c2ccc3c(c2)OCO3)N1
b.) CCOc1ccc(NC(=O)CN(C)C(=O)CCCc2nc3ccccc3c(=O)[nH]2)cc1OCC
c.) CCOc1cc(/C=N/NC(=O)c2ccc(O)cc2)ccc1Oc1nc(Cl)ncc1F
d.) CCOC(=O)N1CCC(O)(c2cc(C)c(C)cc2C)CC1
e.) CCC(CC)c1nnc(NC(=O)CS(=O)(=O)c2ccc(C)cc2)s1
Answer: e. CCC(CC)c1nnc(NC(=O)CS(=O)(=O)c2ccc(C)cc2)s1
