Problem statement: Answer the multiple choice question.
Query: Which drug has a -19.417\% 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 COCCCNCCOCCOc1ccc(Cl)cc1Br.O=C(O)C(=O)O
b O=C(NCCCN1CCCC1=O)c1cccc(S(=O)(=O)N2CCN(c3ccc(F)cc3)CC2)c1
Answer: a. COCCCNCCOCCOc1ccc(Cl)cc1Br.O=C(O)C(=O)O
