Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.460\% 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. CCOC(=O)C1CCN(S(=O)(=O)c2ccc3c4c(cccc24)C(=O)N3)CC1
b. Nc1c(-c2ccccc2)c(CSc2nc3ccccc3[nH]2)nn1-c1cccc(C(=O)O)c1
c. Cl.Nc1ccc(N)c(C(=O)O)c1
d. COc1cc(C)c(S(=O)(=O)N2CCN(C)CC2)cc1C
e. O=S(=O)(Nc1cccnc1)c1cccc(C(F)(F)F)c1
Answer: c. Cl.Nc1ccc(N)c(C(=O)O)c1
