Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.220\% 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 O=C(Nc1cc2c3c(c1)C1CCCC1CN3CC1CCCC21)c1ccc([N+](=O)[O-])cc1
b Cc1nn(CCCC(=O)NC(C)c2ccccc2)c(=O)c2nn(-c3ccccc3)c(C)c12
c CCN1C(=NCC2CC2)N[C@@H](c2cccc(C(F)(F)F)c2)C(C(=O)OC)=C1C
d O=C(CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)N/N=C/c1ccc(F)cc1F
Answer: c. CCN1C(=NCC2CC2)N[C@@H](c2cccc(C(F)(F)F)c2)C(C(=O)OC)=C1C
