Task: Answer the multiple choice question.
Question: Which drug has a 1.536\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cn1nc(-c2ccc(C(=O)Nc3cccnc3)cc2)c2ccccc2c1=O
b: N#Cc1ccccc1OCC(=O)OCC(=O)NC1CCS(=O)(=O)C1
c: Cc1sc(NC(=O)/C=C/C(=O)O)c(C(N)=O)c1-c1ccc(C(C)(C)C)cc1
Answer: a. Cn1nc(-c2ccc(C(=O)Nc3cccnc3)cc2)c2ccccc2c1=O
