Task: Answer the MCQ question.
Query: Which drug exhibits a -22.095% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COc1ccc(CCNC(=O)C/C(C)=N/NC(=O)c2ccc([N+](=O)[O-])cc2Cl)cc1OC
b. O=C(COc1ccc(Cl)cc1Cl)OCC(=O)c1ccc[nH]1
Answer: b. O=C(COc1ccc(Cl)cc1Cl)OCC(=O)c1ccc[nH]1
