Problem statement: Answer the multiple choice question.
Query: Which compound has a 6.460\% 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: CCCC1=NN(c2ccc([N+](=O)[O-])cc2)C(=O)/C1=C/N(C)C
b: O=C1Nc2ccc([N+](=O)[O-])cc2OC1CCN1CCN(Cc2ccc3c(c2)OCO3)CC1
c: CNS(=O)(=O)c1cc(O)c2c(S(=O)(=O)NC)cccc2c1
d: CCCSc1nnc(NC(=O)c2sc3nc(-c4cccs4)ccc3c2N)s1
Answer: a. CCCC1=NN(c2ccc([N+](=O)[O-])cc2)C(=O)/C1=C/N(C)C
