Problem statement: Answer the multiple-choice question.
Query: Which drug has a 5.955\% 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: CCOC(=O)Cn1nc(C)n(-c2ccc(Cl)cc2)c1=O
b: CCOC(=O)C1=C(C)N(c2ccccc2)C(=O)NC1c1cccc([N+](=O)[O-])c1
c: C/C(=N\NC(=O)c1nnn(-c2nonc2N)c1C(C)C)c1ccc2ccccc2c1
d: O=C(Nc1nc(-c2cc(F)ccc2F)cs1)c1ccccn1
Answer: a. CCOC(=O)Cn1nc(C)n(-c2ccc(Cl)cc2)c1=O
