Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.231\% 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: CCCCC(=O)Nc1cccc(-c2nn3c(C)nnc3s2)c1
b: Cc1csc(NC(=O)Cc2ccc(F)cc2)n1
c: COc1ccc(C(=S)N2CCOCC2)cc1OC(=O)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
d: CCc1nnc(NC(=O)C2CCCN2C(=O)Nc2ccccc2)s1
Answer: a. CCCCC(=O)Nc1cccc(-c2nn3c(C)nnc3s2)c1
