Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.408\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.

b NS(=O)(=O)c1ccc(S(=O)(=O)N(Cc2ccccc2F)CC2CCCO2)cc1
c O=C(CNC(=O)c1ccccc1)NCCO
d COc1cccc(C(=O)C(C#N)=C(SC)SC)c1
Answer: b. NS(=O)(=O)c1ccc(S(=O)(=O)N(Cc2ccccc2F)CC2CCCO2)cc1
