Problem statement: Answer the multiple choice question.
Query: Which drug has a 9.866\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=S(=O)(Nc1ccccc1Br)c1cccs1
b: O=C(CSCC(=O)OCC(=O)c1ccc(Br)cc1)Nc1cccc2ccccc12
c: Cc1ccc(S(=O)(=O)N2CCCC2C(=O)Nc2nc3c(s2)CCCC3)cc1
Answer: a. O=S(=O)(Nc1ccccc1Br)c1cccs1
