Task: Answer the multiple choice question.
Question: Which drug exhibits a -20.856\% 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) Cc1ccc(C(=O)N(c2ccccc2)C2CCN(Cc3ccccc3)CC2)s1.Cl
b) O=C(/C=C/c1ccc2c(c1)OCO2)NCCSCc1ccc(Cl)cc1
Answer: a. Cc1ccc(C(=O)N(c2ccccc2)C2CCN(Cc3ccccc3)CC2)s1.Cl
