Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -1.540\% 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 or b without using any other words.
Options:
a.) COc1cccc(N2CC(C(=O)Nc3nnc(SCC(=O)NCc4ccco4)s3)CC2=O)c1
b.) O=C1/C(=C/c2ccccn2)COc2ccccc21
Answer: b. O=C1/C(=C/c2ccccn2)COc2ccccc21
