Task: Answer the multiple-choice question.
Query: Which drug exhibits a -81.921\% 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: CNC(=O)c1cc2c(=O)n3cc(C)ccc3nc2n(C(C)C)c1=N
b: Cc1cc(Cl)ccc1OCC(=O)N1CCN(C)CC1
c: COc1ccc(N2CCN(C(=O)Cn3nnc(-c4cccs4)n3)CC2)cc1
d: CC(CC(=O)N(C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O)c1ccccc1
e: COc1cc(C(O)C(=O)O)ccc1O
Answer: a. CNC(=O)c1cc2c(=O)n3cc(C)ccc3nc2n(C(C)C)c1=N
