Task: Answer the multiple-choice question.
Query: Which drug exhibits a -13.509\% 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, or d without using any other words.
Options:
a.) CCN1CCN(CC(=O)Nc2ccc(C)c(Br)c2)CC1.Cl
b.) COC(=O)c1ccc(N=C2S/C(=C\c3cc(C)n(-c4cccnc4)c3C)C(=O)N2C)cc1
c.) O=C(Nc1cccc2ccccc12)c1ccc([N+](=O)[O-])o1
d.) O=C(COC(=O)Cc1ccsc1)NCc1ccccc1
Answer: a. CCN1CCN(CC(=O)Nc2ccc(C)c(Br)c2)CC1.Cl
