Problem statement: Answer the multiple choice question.
Question: Which drug has a -1.427\% 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. O=C(Nc1ccc(CN2CCOCC2)cc1)c1cccs1
b. CCOC(=O)C(Oc1ccc(=O)[nH]n1)C(C)=O
c. CS(=O)(=O)N(CC(=O)NCc1ccco1)c1ccc(OCc2ccccc2)cc1
d. COc1ccc(C)cc1NC(=O)COCC(=O)O
Answer: a. O=C(Nc1ccc(CN2CCOCC2)cc1)c1cccs1
