Task: Answer the MCQ question.
Query: Which drug exhibits a -21.297% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=C1CC(c2ccco2)CC(O)=C1C=Nc1cc(Cl)ccc1O
b. CC(=Nc1ccccc1)c1sc2ccccc2c1O
c. CCCn1c(-c2ccc(C(=O)OC)cc2)nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1
d. CCC(=O)OCC(=O)Nc1cc([N+](=O)[O-])ccc1OC
e. CCOC(=O)C1CCCN(C(=O)CC(c2ccccc2)c2ccccc2)C1
Answer: e. CCOC(=O)C1CCCN(C(=O)CC(c2ccccc2)c2ccccc2)C1
