Task: Answer the multiple choice question.
Query: Which drug has a 4.938\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=S(=O)(c1ccccc1Cl)N1CCC(O)(c2ccc3c(c2)OCO3)CC1
b CCC1C(=NO)C(CC)C(c2ccccc2)NC1c1ccccc1
Answer: a. O=S(=O)(c1ccccc1Cl)N1CCC(O)(c2ccc3c(c2)OCO3)CC1
