Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -1.284\% 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 additional words.
Options:
a.) O=C(c1nn2c(C(F)(F)F)cc(-c3cccs3)nc2c1Br)N1CCCc2ccccc21
b.) COc1cccc2c1OCC(C(=O)Nc1nccs1)=C2
c.) Cc1cc([N+](=O)[O-])ccc1NC(=O)c1sc2ncn(CC(=O)N3CCOCC3)c(=O)c2c1C
d.) CCN(CC)C(=O)CSc1nnc(CSc2ncccn2)n1C
e.) Cc1ccc(CNC(=O)C(=O)c2cn(CC(=O)N3CCOCC3)c3ccccc23)cc1
Answer: d. CCN(CC)C(=O)CSc1nnc(CSc2ncccn2)n1C
