Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.897\% 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 CN(CC(=O)NC1CC(C)(C)NC(C)(C)C1)S(=O)(=O)c1ccc(Br)cc1
b COc1cccc(/C=C/C(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)c1OC
c O=C(c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)N1CCN(Cc2ccccc2)CC1
d CCN(CC)c1nc2c3c(nc4c(c3c1C#N)CC(=O)N4c1ccc(Cl)cc1)NC(C)=N2
Answer: c. O=C(c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)N1CCN(Cc2ccccc2)CC1
