Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.948\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CC(=O)c1cccc(NC(=O)CCCSc2ccccc2)c1
b) CCOC(=O)C1C(=O)C=C(C)C(C(=O)OCC)C1c1ccc(OC)cc1
c) Cc1ccc(OCC(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)cc1C
Answer: b. CCOC(=O)C1C(=O)C=C(C)C(C(=O)OCC)C1c1ccc(OC)cc1
