Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.833\% 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 Cn1c(Sc2ccc(Br)cc2)c(C=O)c2ccccc21
b Cc1ccc(N(CC(=O)NC(C)c2ccccc2)S(=O)(=O)c2c(C)n[nH]c2C)cc1
Answer: a. Cn1c(Sc2ccc(Br)cc2)c(C=O)c2ccccc21
