Task: Answer the multiple-choice question.
Question: Which drug has a -1.873\% 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 other words.
Options:
a: O=C(Nc1c2c(nc3ccccc13)CCCC2)c1ccccc1Cl
b: COc1c2c(nc3occc13)C(CC=C(C)C)(OC)C(O)CC2
c: O=c1cc(-c2ccc(O)c(O)c2)oc2cc(O)c(C3OC(CO)C(O)C(O)C3O)c(O)c12
d: CN1CCN(C(=O)c2cc(S(=O)(=O)Nc3ccccc3F)c(Cl)cc2Cl)CC1
e: O=C(CN1C(=O)NC2(CCCCC2)C1=O)N1CCN(C(=O)c2cccs2)CC1
Answer: e. O=C(CN1C(=O)NC2(CCCCC2)C1=O)N1CCN(C(=O)c2cccs2)CC1
