Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.972\% 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: CCOC(=O)c1c(C)nc2c(c1-c1cc(OC)ccc1OC)C(=O)CC(C)(C)C2
b: CN(CC(=O)NCc1ccccn1)S(=O)(=O)c1cc(Cl)ccc1Cl
c: CCNC(=S)N1CCc2cc(OC)c(OC)cc2C1COc1ccc(F)cc1
d: CCOC(=O)C1CCCN(C2CC(=O)N(c3cccc(C(F)(F)F)c3)C2=O)C1.Cl
e: CCC1=NN(C(=O)Cc2ccc([N+](=O)[O-])cc2)C(O)(C(F)(F)F)C1
Answer: d. CCOC(=O)C1CCCN(C2CC(=O)N(c3cccc(C(F)(F)F)c3)C2=O)C1.Cl
