Task: Answer the multiple-choice question.
Query: Which drug exhibits a -3.960\% 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 CCOC(=O)C1CCN(C(=O)Cc2ccc(-c3ccccc3)cc2)CC1
b O=C(c1ccc(-c2cccc(C(F)(F)F)c2)o1)N1CCN(c2ccccc2O)CC1
c CCn1nnc(NC(=O)c2sc3ccccc3c2Cl)n1
Answer: a. CCOC(=O)C1CCN(C(=O)Cc2ccc(-c3ccccc3)cc2)CC1
