Task: Answer the multiple choice question.
Query: Which drug has a -0.504\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=[N+]([O-])c1ccccc1N=Nc1ccc(O)cc1
b) O=C(NCc1ccncc1)C(=O)NCC1OCCN1S(=O)(=O)c1ccc(Br)cc1
c) O=C(OCCN(C1=NS(=O)(=O)c2ccccc21)c1ccccc1Cl)c1ccc(Cl)cc1
d) Cc1ccc(S(=O)(=O)N(C)C)cc1NC(=O)c1cccnc1Oc1ccccc1
Answer: c. O=C(OCCN(C1=NS(=O)(=O)c2ccccc21)c1ccccc1Cl)c1ccc(Cl)cc1
