Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.943\% 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=c1c(C(c2ccccc2)c2c(O)nc3n(c2=O)CCCS3)c(O)nc2n1CCCS2
(b) Cc1ccc(C)c(NC(=O)COC(=O)c2ccc3ccccc3n2)c1
Answer: a. O=c1c(C(c2ccccc2)c2c(O)nc3n(c2=O)CCCS3)c(O)nc2n1CCCS2
