Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 7.830\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(NCCCN1CCCC1=O)C1CCN(S(=O)(=O)c2c(Cl)cccc2Cl)CC1
b: CCN(CC(=O)Nc1ccc(OC)cc1)C(=O)c1ccc2[nH]c3c(c2c1)CC(C)CC3
c: CNS(=O)(=O)c1ccc2c3c(cccc13)C(=O)N2C
Answer: c. CNS(=O)(=O)c1ccc2c3c(cccc13)C(=O)N2C
