Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.493\% 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: COc1ccccc1[N+](=O)[O-]
b: O=S(=O)(c1ccc(N2CC=C(c3ccccc3)CC2)nc1)N1CCCC1
c: O=C(CN(C1CCCCC1)S(=O)(=O)c1ccc(Cl)cc1)NCc1cccnc1
d: O=C(CSc1nccn1-c1ccccc1)c1ccc(Br)cc1
e: COc1cccc(C2NC(=O)c3ccccc3O2)c1OCc1ccccc1F
Answer: d. O=C(CSc1nccn1-c1ccccc1)c1ccc(Br)cc1
