Task: Answer the multiple-choice question.
Question: Which drug exhibits a -8.386% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC1(C)C(=O)OC(c2cccn2-c2cccc([N+](=O)[O-])c2)C2(CCCCC2)C1=O
b COc1ccc(OC)c(-n2c(C)cc(C=O)c2C)c1
c CCN1CC=C(c2c[nH]c3ccccc23)CC1
d COC(=O)CNC(=O)c1cn(CC(C)C)c(=O)c2cc(OC)c(OC)cc12
Answer: c. CCN1CC=C(c2c[nH]c3ccccc23)CC1
