Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.582\% 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] CCS(=O)(=O)N1CCC(C(=O)N2CCOCC2)CC1
[b] O=C(Cn1c(-c2ccccn2)nc2ccccc21)N/N=C/c1ccccn1
Answer: b. O=C(Cn1c(-c2ccccn2)nc2ccccc21)N/N=C/c1ccccn1
