Problem statement: Answer the multiple choice question.
Question: Which drug has a 19.219\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=[N+]([O-])c1ccc(N2CCC(O)CC2)nc1
b. O=C(CS(=O)c1ccc(C(F)(F)F)cc1[N+](=O)[O-])Oc1ccc(Cl)cc1
c. OC1NC(=S)N(c2ccccc2)C1O
d. CCOC(=O)C1=C(C)N(c2ccccc2)C(=O)/C1=C\c1cccs1
e. O=C(NCCCc1ccccc1)c1ccc(F)cc1
Answer: b. O=C(CS(=O)c1ccc(C(F)(F)F)cc1[N+](=O)[O-])Oc1ccc(Cl)cc1
