Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -16.960\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(Cn1c(=O)c2sccc2n(Cc2ccc([N+](=O)[O-])cc2)c1=O)NCCc1ccccc1
b) CCC(c1nnnn1Cc1ccc(OC)cc1)N(CCCO)Cc1cc2cc3c(cc2[nH]c1=O)OCO3
Answer: a. O=C(Cn1c(=O)c2sccc2n(Cc2ccc([N+](=O)[O-])cc2)c1=O)NCCc1ccccc1
