Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.446\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(Nc1cccc(CNCCc2c[nH]c3ccccc23)c1)c1ccccc1Cl.O=C(O)C(=O)O
b O=C(Cc1cnc2ncnn2c1)N1CCc2c([nH]c3ccccc23)C1c1ccccn1
c Cn1c(-c2ccc(F)cc2)cnc1SCC(=O)N1CCCc2ccccc21
d COc1ccc(S(=O)(=O)N2CCN(CC(=O)Nc3cc(C(F)(F)F)ccc3Cl)CC2)cc1
Answer: a. O=C(Nc1cccc(CNCCc2c[nH]c3ccccc23)c1)c1ccccc1Cl.O=C(O)C(=O)O
