Task: Answer the multiple choice question.
Question: Which drug has a -4.519% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COc1ccc(CNn2c(-c3cccs3)nc3ccccc3c2=O)cc1OC
b) CN(C)CCNC(=O)C(=O)NCC1OCCN1S(=O)(=O)c1ccc([N+](=O)[O-])cc1
c) CCOC(=O)CCSc1nc(N2CCOCC2)c2c(c1C#N)CC(C)(C)OC2
Answer: a. COc1ccc(CNn2c(-c3cccs3)nc3ccccc3c2=O)cc1OC
