Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.273\% human ether-à-go-go related gene (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) CCN1/C(=C2\C(=O)N(c3ccccc3)N=C2C)C=Cc2cc(C)ccc21
b) Cc1ccc(/C=C2\S/C(=N/S(=O)(=O)c3cccs3)NC2=O)cc1
c) COc1ccc(CNC(=O)CCc2nnc3ccc(N4CCC5(CC4)OCCO5)nn23)cc1
d) Cc1ccc(OCCCCNC2CCCCC2)c(C)c1.O=C(O)C(=O)O
Answer: c. COc1ccc(CNC(=O)CCc2nnc3ccc(N4CCC5(CC4)OCCO5)nn23)cc1
