Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.063\% 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, b, c, or d without using any additional words.
Options:
a. Fc1ccc(-[n+]2nc(Nc3ccccc3)sc2-c2c3ccccc3cc3ccccc23)cc1.[Cl-]
b. CCCC(=O)N1CCN(S(=O)(=O)c2cc(Cl)ccc2OC)CC1
c. O=C(O)c1cc2sccc2s1
d. CCNC(=O)C(=O)N/N=C/c1cc([N+](=O)[O-])ccc1O
Answer: d. CCNC(=O)C(=O)N/N=C/c1cc([N+](=O)[O-])ccc1O
