Task: Answer the MCQ question.
Question: Which drug exhibits a 9.441\% 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 other words.
Options:
[a] O=C1CCC(c2ccc(-n3ccnc3)cc2)=NN1
[b] COc1ccc(CNCCc2ccccc2)cc1OCC(N)=O
[c] CCOC(=O)c1ccccc1NC(=O)CC(C)CC(=O)O
[d] COc1ccc(N2C(=O)/C(=C/c3ccc([N+](=O)[O-])cc3)N=C2C)cc1
Answer: a. O=C1CCC(c2ccc(-n3ccnc3)cc2)=NN1
