Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.346\% 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 other words.
Options:
a) CC(O)C(NS(=O)(=O)c1ccc(Cl)cc1)C(=O)OCC(=O)c1c[nH]c2ccccc12
b) Cc1ccc(OCCOc2ccc(Br)cc2/C=N\NC(N)=O)cc1
c) Cc1ccc(C)c(N2CCN(S(=O)(=O)c3ccc(-c4ccc(=O)[nH]n4)o3)CC2)c1
d) O=c1oc(-c2ccc(Br)cc2)nc2ccccc12
e) Cc1cccc2sc(NC(=O)C3CCN(C(=O)c4ccco4)CC3)nc12
Answer: d. O=c1oc(-c2ccc(Br)cc2)nc2ccccc12
