Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 21.845% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(CCn1ccc([N+](=O)[O-])n1)Nc1nccs1
[b] O=c1[nH]c(=O)n(C2CCCCCC2)c(O)c1C=NCCCN1CCOCC1
Answer: a. O=C(CCn1ccc([N+](=O)[O-])n1)Nc1nccs1
