Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.523% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC(=O)N(C(C)=O)c1nc(-c2ccccc2)cn1/N=C/c1cccc([N+](=O)[O-])c1
(b) O=[N+]([O-])c1ccc(Cl)c(Cl)c1Cl
(c) COc1cccc(/C=N/NC(=O)CCCC(=O)Nc2ccc(Br)cc2)c1
(d) C/C(CC(=O)NC1CCCC1)=N\NC(=O)Cc1csc(N)n1
Answer: a. CC(=O)N(C(C)=O)c1nc(-c2ccccc2)cn1/N=C/c1cccc([N+](=O)[O-])c1
