Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.812% 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: COC(=O)c1ccc(NC(C)C(=O)OC)c([N+](=O)[O-])c1
b: O=C(Nc1ccc(NC(=O)c2cc3ccccc3o2)cc1)c1ccc2c(c1)OCCO2
c: COc1ccc(C2=C(N)c3ccccc3C2=O)cc1
d: CC(C)c1nnc(NC(=O)CCC(=O)NC2CC2)s1
Answer: a. COC(=O)c1ccc(NC(C)C(=O)OC)c([N+](=O)[O-])c1
