Task: Answer the MCQ question.
Question: Which drug has a 13.929\% 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=C(CSc1nnc(Nc2ccccc2F)s1)NC1CC1
b. Cc1ccc(S(=O)(=O)CCC(=O)O)cc1C
c. O=C(NCCc1ccccc1Cl)c1ccc2nc3ccccc3c(=O)n2c1
d. Oc1[nH]c2ccccc2c1C=Nc1ccccc1
e. O=C(CNC(=O)c1ccc(Br)cc1)N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12
Answer: e. O=C(CNC(=O)c1ccc(Br)cc1)N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12
