Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.790\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) O=C(O)CCN1CC2([N+](=O)[O-])CC=C(OCCO)C([N+](=O)[O-])(C1)C2
b.) O=C(c1ccccc1[N+](=O)[O-])N1CC2C3C=CC(C3)C2C1
c.) Cn1cc[n+](C)c1P(=S)(c1ccccc1)c1ccccc1.[Cl-]
d.) CCN1CCCC1CNC(=O)c1cc(S(N)(=O)=O)ccc1OC
e.) NC(=O)c1ccc(NC(=O)COC(=O)c2ccc([N+](=O)[O-])cc2)cc1
Answer: b. O=C(c1ccccc1[N+](=O)[O-])N1CC2C3C=CC(C3)C2C1
