Task: Answer the multiple choice question.
Question: Which drug has a 3.000\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(O)CSc1ccc(S(=O)(=O)N2CCCC2)cn1
b. CCn1c(SCC(=O)Nc2cc(C(C)(C)C)nn2-c2ccccc2)nnc1-c1cccs1
Answer: a. O=C(O)CSc1ccc(S(=O)(=O)N2CCCC2)cn1
