Task: Answer the multiple choice question.
Query: Which drug has a 7.464% 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 additional words.
Options:
a O=[N+]([O-])C12CNCN(CN(Cc3ccccc3)C1)C2
b Cc1c(-c2ccc(Br)cc2)nc2ccccn12
c CN1CCN(C(=O)CSc2ccc(Cl)cc2)CC1
d Cc1ccc2nc(N3CCN(C)CC3)c(C#N)cc2c1
Answer: a. O=[N+]([O-])C12CNCN(CN(Cc3ccccc3)C1)C2
