Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -3.826\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=[N+]([O-])/C=C/c1c(OCc2ccccc2)ccc2ccccc12
(b) Cc1ccc(S(=O)(=O)NCCC(=O)Nc2cc(S(=O)(=O)N(C)C)ccc2C)cc1C
Answer: a. O=[N+]([O-])/C=C/c1c(OCc2ccccc2)ccc2ccccc12
