Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.797\% 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. C=CCOc1ccc(Br)cc1CNCC.Cl
b. COc1ccc(C(C)NC(=O)c2ccc(Cl)cc2)cc1OC
c. Cc1ccc(NC(=S)NC(=O)c2ccccc2)cc1NC(=S)NC(=O)c1ccccc1
d. CCOC(=O)C1(Cc2ccccc2)C(=O)Nc2ccccc21
Answer: d. CCOC(=O)C1(Cc2ccccc2)C(=O)Nc2ccccc21
