Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.930\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CC1=C(C#N)C(c2ccc(O)cc2)C2=C(CC(C)(C)CC2=O)N1
b. COc1ccc(OC)c(NC(=O)C2CCCN(S(=O)(=O)c3cccc4cccnc34)C2)c1
Answer: a. CC1=C(C#N)C(c2ccc(O)cc2)C2=C(CC(C)(C)CC2=O)N1
