Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 17.784\% 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(NNC(=O)C(O)c1ccccc1)NC1CCCCC1
b. CN(Cc1ccccc1)C(=O)COC(=O)CNS(=O)(=O)c1ccc2ccccc2c1
c. Cc1c(C(=O)Nc2ccc(Cl)cc2)c2ccccn2c1C(=O)c1ccc([N+](=O)[O-])cc1
d. O=C(Nc1c(C(=O)O)oc2ccc(Br)cc12)c1ccccc1
e. Cc1ccc2cc(CN(c3ccccc3)S(=O)(=O)c3ccccc3)c(=O)[nH]c2c1
Answer: a. O=C(NNC(=O)C(O)c1ccccc1)NC1CCCCC1
