Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.987\% 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 additional words.
Options:
[a] COc1ccc(CCn2c(NN=C(C)C)nc3c2c(=O)[nH]c(=O)n3C)cc1
[b] O=C(COC(=O)c1ccc2ccccc2n1)NCc1ccccc1
[c] Cc1ccc(C2CN=NC23CCc2ccccc2C3=O)cc1
[d] O=[N+]([O-])c1nn(-c2ccccc2)[n+]([O-])c1N1CCN(c2ccccc2)CC1
Answer: a. COc1ccc(CCn2c(NN=C(C)C)nc3c2c(=O)[nH]c(=O)n3C)cc1
