Task: Answer the multiple choice question.
Query: Which compound has a 3.519\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cc2[nH]c(C(=O)N(C)C3CCS(=O)(=O)C3)cc2c(OC)c1OC
b: CCCCSc1nnc([C@@H]2CCCN2C(=O)OC(C)(C)C)o1
c: Cl.c1ccc2c(Nc3nc(N4CCOCC4)c4ccccc4n3)cccc2c1
d: Fc1ccc2[nH]c3c(Cl)ncnc3c2c1
e: Cc1nn2c(nc1=O)SCC(c1ccccc1)=N2
Answer: e. Cc1nn2c(nc1=O)SCC(c1ccccc1)=N2
