Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.420\% 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 COc1ccc(-c2nnc(NC(=O)c3cccs3)s2)c(OC)c1
b COc1cccc(NC(=O)c2cc(=O)c3ccccc3o2)c1
c CCCCNC(=O)C1=C(N)C(C(=O)Nc2ccc(C)c(S(=O)(=O)N3CCCCC3)c2)SC1=Nc1ccc(C)cc1C
d Cc1nn(Cc2ccccc2)c(C)c1C(=O)NCc1ccccc1F
Answer: a. COc1ccc(-c2nnc(NC(=O)c3cccs3)s2)c(OC)c1
