Problem statement: Answer the multiple-choice question.
Question: Which drug has a 8.472\% 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 additional words.
Options:
(a) O=C1CCC([N+](=O)[O-])C(c2ccc(Cl)c([N+](=O)[O-])c2)N1
(b) O=c1[nH]c(N/N=C/c2ccc(O)cc2)nc2ccccc12
Answer: a. O=C1CCC([N+](=O)[O-])C(c2ccc(Cl)c([N+](=O)[O-])c2)N1
