Task: Answer the multiple-choice question.
Query: Which drug exhibits a 17.506\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCOc1ccccc1N(CC(=O)N1CCc2ccccc2C1)S(C)(=O)=O
(b) COc1ccc(N(CC(=O)NCc2ccc(C)cc2)S(=O)(=O)c2c(C)nn(C)c2C)cc1
(c) O=S(=O)(NCc1cn2ccccc2n1)c1cccs1
(d) CCn1c(=O)c2sccc2n(Cc2cc(C(=O)OC)ccc2OC)c1=O
Answer: a. CCOc1ccccc1N(CC(=O)N1CCc2ccccc2C1)S(C)(=O)=O
