Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.087\% 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.) O=C(O)c1ccc2c(c1)CCC2
b.) CCOc1ccc(Br)cc1S(=O)(=O)NC1CCCC1
c.) Cc1ccc2c(c1)C1CC(C)(O2)N(c2cccc(C(=O)NCc3ccccn3)c2)C(=O)N1
d.) CCN1CCCc2cc(CN(CCN3CCOCC3)C(=S)Nc3ccccc3C)ccc21
e.) O=C(Nc1nnc(-c2cc(Cl)ccc2Cl)o1)C1=COCCO1
