Task: Answer the multiple-choice question.
Query: Which compound has a -1.475\% 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(NC1CCCCC1)c1cc(Cl)ccc1[N+](=O)[O-]
b. Cc1ccc(S(=O)(=O)Nc2csc(C)c2C(=O)O)cc1
c. C/C(=C\c1ccccc1)CN1CCN(C(C)C)C(CCO)C1
d. O=C1C(C=Nc2ccccc2)=C(O)c2ccccc21
e. N#Cc1cnn(-c2ccccc2)c1NC(=O)c1ccccc1F
Answer: d. O=C1C(C=Nc2ccccc2)=C(O)c2ccccc21
