Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.967\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(O)C(=O)O.OC(CNc1ccccc1)Cn1ccc2ccccc21
[b] CCCCC(=O)c1c(C)cc(C)[nH]c1=O
[c] COc1cccc(NC(=O)N2CCCc3ccccc32)c1
[d] O=C1CC(N2CCOCC2)=NN1c1ccc([N+](=O)[O-])cc1
Answer: a. O=C(O)C(=O)O.OC(CNc1ccccc1)Cn1ccc2ccccc21
