Task: Answer the multiple choice question.
Query: Which drug has a -0.560\% 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 additional words.
Options:
(a) C=CCCC(=O)Nc1ccc(Br)cn1
(b) O=C(Nc1ccc(C(=O)O)cc1)/C(=C\c1cccc([N+](=O)[O-])c1)NC(=O)c1ccc(Br)o1
(c) CC(=O)c1ccc(S(=O)(=O)Nc2cccc(-c3ccc4nncn4n3)c2)cc1
(d) CCNC(=O)CC1SC(=Nc2ccc(Cl)cc2)N(CC)C1=O
Answer: d. CCNC(=O)CC1SC(=Nc2ccc(Cl)cc2)N(CC)C1=O
