Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 1.669\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(Nc1cccc(F)c1)Nc1ccc(Cl)cn1
b) O=C(CCNS(=O)(=O)c1ccc(Br)cc1)NCc1ccco1
c) O=C(CCCOc1ccc(Cl)cc1Cl)NCCCO
d) CCc1ccccc1N(CC(=O)NC1CCCCC1)C(=O)CCCC(=O)Nc1ccccn1
Answer: a. O=C(Nc1cccc(F)c1)Nc1ccc(Cl)cn1
