Problem statement: Answer the multiple-choice question.
Question: Which drug has a 4.027\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COCCn1c(N/N=C(C)/C=C/c2ccccc2)nc2c1c(=O)[nH]c(=O)n2C
[b] COC(=O)C(NC(C)=O)(Nc1ccc(Br)cc1)C(=O)OC
[c] COc1ccc(OC)c([N+](=O)[O-])c1C(N)=O
Answer: a. COCCn1c(N/N=C(C)/C=C/c2ccccc2)nc2c1c(=O)[nH]c(=O)n2C
