Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.548\% 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 COc1ccc(C(=O)c2ccc(N(C)C)cc2)c(OC)c1
b CSc1ccc(C2C(C#N)=C(N)N(c3ccccc3)C3=C2C(=O)CCC3)cc1
c CCOC(=O)Cc1csc(NC(=O)c2cc3ccccc3o2)n1
d CCCCCOc1ccc(CSC(=N)N)cc1[N+](=O)[O-].Cl
Answer: b. CSc1ccc(C2C(C#N)=C(N)N(c3ccccc3)C3=C2C(=O)CCC3)cc1
