Task: Answer the multiple-choice question.
Query: Which drug has a -7.960\% 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] CCN(CC)CCn1c2c(c(SCC(=O)NCc3ccccc3)nc1=O)CCC2
[b] O=C(CCNC(=O)c1ccc([N+](=O)[O-])cc1)N/N=C/c1ccc(F)cc1
Answer: b. O=C(CCNC(=O)c1ccc([N+](=O)[O-])cc1)N/N=C/c1ccc(F)cc1
