Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.464\% 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] CSc1ncc(Cl)c(C(=O)Nc2ccccc2C)n1
[b] CC1=C(C(=O)OCc2ccccc2)C(c2ccccc2)NC(=O)N1
[c] O=C(NNC(=O)C1CCC1)c1ccccc1F
[d] CCOC(=O)C1CCN(C(=O)c2cc3c(ccc4ccccc43)o2)CC1
Answer: b. CC1=C(C(=O)OCc2ccccc2)C(c2ccccc2)NC(=O)N1
