Task: Answer the multiple choice question.
Query: Which compound has a 6.893\% 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 other words.
Options:
a.) O=C(CN1C(=O)/C(=C\c2cccc(Cl)c2)Sc2ccccc21)NCCCN1CCOCC1
b.) COC(=O)c1c(C)[nH]c(C(=O)NCCc2ccc(S(N)(=O)=O)cc2)c1C
c.) O=C(CSc1nc(Nc2ccccc2)nc(N2CCOCC2)n1)N1CCCC1
d.) Cc1ccsc1-c1nc(-c2ccccc2)c(-c2ccccc2)[nH]1
e.) CC1(C)CC(=O)C2=C(C1)OC([N+](=O)[O-])C2c1ccccc1
Answer: e. CC1(C)CC(=O)C2=C(C1)OC([N+](=O)[O-])C2c1ccccc1
